由真值表的逻辑函数式：
Y=O’3
于是得设计电路：
2. 试用二进制计数器 74LS191 接成 24 秒倒计时器。
设计说明：首先将开关 j1 置地端，这时给组合逻辑电路置入“24”。然后 将 j1 置 VCC，电路开始倒计时。计时过程中将 j1 置地可以暂停计时，j1 置 VCC 后继续计时。当计时结束后（即为“00”时）停止计时。若要重 新计时，只需重新启动即可。
2、74LS191 功能表：
三、实验内容：
1. 利用同步二进制可逆计数器 74LS191 接成同步八进制计数器。
设计思路：
74LS191 是 16 进制同步计数器，要做 8 进制计时器，就要在输出为 8 时给输入端置 0。 于是的 8 进制计数器真值表。
74HC191中文资料
Counting is inhibited by a HIGH level on the count enable (CE) input. When CE is LOW internal state changes are initiated synchronously by the LOW-to-HIGH transition of the clock input. The up/down (U/D) input signal determines the direction of counting as indicated in the function table. The CE input may go LOW when the clock is in either state, however, the LOW-to-HIGH CE transition must occur only when the clock is HIGH. Also, the U/D input should be changed only when either CE or CP is HIGH.
The 74HC/HCT191 are asynchronously presettable 4-bit binary up/down counters. They contain four master/slave flip-flops with internal gating and steering logic to provide asynchronous preset and synchronous count-up and count-down operation.

August 1986Revised February 1999DM74LS191 Synchronous 4-Bit Up/Down Counter with Mode Control© 1999 Fairchild Semiconductor Corporation DS006405.prf DM74LS191Synchronous 4-Bit Up/Down Counter with Mode ControlGeneral DescriptionThe DM74LS191 circuit is a synchronous, reversible, up/down counter. Synchronous operation is provided by hav-ing all flip-flops clocked simultaneously, so that the outputs change simultaneously when so instructed by the steering logic. This mode of operation eliminates the output count-ing spikes normally associated with asynchronous (ripple clock) counters.The outputs of the four master-slave flip-flops are triggered on a LOW-to-HIGH level transition of the clock input, if the enable input is LOW. A HIGH at the enable input inhibits counting. Level changes at either the enable input or the down/up input should be made only when the clock input is HIGH. The direction of the count is determined by the level of the down/up input. When LOW, the counter counts up and when HIGH, it counts down.The counter is fully programmable; that is, the outputs may be preset to either level by placing a LOW on the load input and entering the desired data at the data inputs. The output will change independent of the level of the clock input. This feature allows the counters to be used as modulo-N divid-ers by simply modifying the count length with the preset inputs.The clock, down/up, and load inputs are buffered to lower the drive requirement; which significantly reduces the num-ber of clock drivers, etc., required for long parallel words.Two outputs have been made available to perform the cas-cading function: ripple clock and maximum/minimum count.The latter output produces a high-level output pulse with a duration approximately equal to one complete cycle of the clock when the counter overflows or underflows. The ripple clock output produces a low-level output pulse equal in width to the low-level portion of the clock input when an overflow or underflow condition exists. The counters can be easily cascaded by feeding the ripple clock output to the enable input of the succeeding counter if parallel clocking is used, or to the clock input if parallel enabling is used.The maximum/minimum count output can be used to accomplish look-ahead for high-speed operation.Featuress Counts binarys Single down/up count control line s Count enable control input s Ripple clock output for cascadings Asynchronously presettable with load control s Parallel outputss Cascadable for n-bit applications s Average propagation delay 20 ns s T ypical clock frequency 25 MHz s T ypical power dissipation 100 mWOrdering Code:Devices also available in Tape and Reel.

1. Renesas Technology Corporation puts the maximum effort into making semiconductor products better and more reliable, but there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury, fire or property damage. Remember to give due consideration to safety when making your circuit designs, with appropriate measures such as (i) placement of substitutive, auxiliary circuits, (ii) use of nonflammable material or (iii) prevention against any malfunction or mishap.

Fairchild’s Anti-Counterfeiting Policy is also stated on our external website,, under Sales Support .Counterfeiting of semiconductor parts is a growing problem in the industry. All manufactures of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed application, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild’s quality standards for handing and storage and provide access to Fairchild’s full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address and warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.®FDZ191P Rev.F3 (W)7。

逻辑功能:
(1)由于每输入16个CLK 脉冲触发器的状态一循环，并 在输出端C产生一进位信号，故为16进制计数器。若 二进制数码的位数为n，而计数器的循环周期为2n， 这样计数器又叫二进制计数器。将计数器中能计到的 最大数称为计数器的容量，为2n－1.
