74LS属于TTL类型的集成电路，而74HC属于CMOS集成电路。
LS、HC 二者高电平低电平定义不同，HC高电平规定为0.7倍电源电压，低电平规定为0.3倍电源电压。
LS规定高电平为2.0V，低电平为0.8V。
带负载特性不同。
HC上拉下拉能力相同，LS 上拉弱而下拉强。
输入特性不同。
HC输入电阻很高，输入开路时电平不定。
LS输入内部有上拉，输入开路时为高电平。
（1）74LS系列是“低功耗肖特基TTL”，统称74LS系列。
其改进型为“先进低功耗肖特基TTL”，既74ALS系列，它的性能比74LS更好。
（2）74HC系列，它具有CMOS的低功耗和相当于74LS高速度的性能，属于一种高速低功耗产品。
（3）上述两者的工作频率都在30mHz以下，74ALS略高，可达50mHz。
（4）但它们的工作电压却大不相同：74LS系列为5V，74HC系列为2~6V。
（5）扇出能力：74LS系列为20，而74HC系列在直流时则高达1000以上，但在交流时很低，由工作频率决定74HC属于CMOS系列，输入阻抗高，输出电压高（4.9V为逻辑1），驱动能力差；74LS属于TTL系列，输出电压较低（3.5V为逻辑1），驱动能力较强；与单片机匹配，关系不大，但尽量用同一类型的芯片，即74HC 系列74系列芯片功能大全7400 TTL 2输入端四与非门7401 TTL

Registers,and Forces ConsumptionAll Outputs Low•Output Edge-Control Circuitry Minimizes Switching Noise in an Unterminated LineThis 25-bit 1:1or 14-bit 1:2configurable registered buffer is designed for 1.7-V to 1.9-V VCC operation.In the 1:1pinout configuration,only one device per DIMM is required to drive nine SDRAM loads.In the 1:2pinout configuration,two devices per DIMM are required to drive 18SDRAM loads.All inputs are SSTL_18,except the reset (RESET)and control (Cn)inputs,which are LVCMOS.All outputs are edge-controlled circuits optimized for unterminated DIMM loads and meet SSTL_18specifications.The SN74SSTUB32864operates from a differential clock (CLK and CLK).Data are registered at the crossing of CLK going high and CLK going low.The C0input controls the pinout configuration of the 1:2pinout from register-A configuration (when low)to register-B configuration (when high).The C1input controls the pinout configuration from 25-bit 1:1(when low)to 14-bit 1:2(when high).C0and C1should not be switched during normal operation.They should be hard-wired to a valid low or high level to configure the register in the desired mode.In the 25-bit 1:1pinout configuration,the A6,D6,and H6terminals are driven low and are do-not-use (DNU)pins.In the DDR2RDIMM application,RESET is specified to be completely asynchronous with respect to CLK and CLK.Therefore,no timing relationship can be ensured between the two.When entering reset,the register is cleared,and the data outputs are driven low quickly,relative to the time required to disable the differential input receivers.However,when coming out of reset,the register becomes active quickly,relative to the time required to enable the differential input receivers.As long as the data inputs are low,and the clock is stable during the time from the low-to-high transition of RESET until the input receivers are fully enabled,the design of the SN74SSTUB32864ensures that the outputs remain low,thus ensuring there will be no glitches on the output.To ensure defined outputs from the register before a stable clock has been supplied,RESET must be held in the low state during power up.The device supports low-power standby operation.When RESET is low,the differential input receivers are disabled,and undriven (floating)data,clock,and reference voltage (V REF )inputs are allowed.In addition,when RESET is low,all registers are reset and all outputs are forced low,except QERR.The LVCMOS RESET and Cn inputs always must be held at a valid logic high or low level.ORDERING

limited built-in ESD protection.The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.The device also supports low-power active operation by monitoring both system chip select(DCS and CSR) inputs and gates the Qn outputs from changing states when both DCS and CSR inputs are high.If either DCS or CSR input is low,the Qn outputs function normally.The RESET input has priority over the DCS and CSR control and,when driven low,forces the Qn outputs low.If the DCS control functionality is not desired,the CSR input can be hard-wired to ground,in which case the setup-time requirement for DCS is the same as for the other D data inputs.To control the low-power mode with DCS only,the CSR input should be pulled up to V CC through a pullup resistor.The two V REF pins(A3and T3)are connected together internally by approximately150Ω.However,it is necessary to connect only one of the two V REF pins to the external V REF power supply.An unused V REF pin should be terminated with a V REF coupling capacitor.2Submit Documentation Feedback Copyright©2006–2007,Texas Instruments

7404芯片
7404芯片7404芯片，全称为SN7404芯片，是一种六通道反相器芯片，属于TTL逻辑家族。
它的主要功能是将输入信号取反，并输出给下一个级联的电路。
这种芯片常用于数字逻辑电路中进行信号处理和逻辑运算。
SN7404芯片的引脚共有14个，分为两行，每行7个引脚。
其中，左边一行的引脚分别为GND（接地）、1A、1Y、2A、2Y、3A、3Y，右边一行的引脚分别为VCC（电源）、4A、4Y、5A、5Y、6A、6Y。
其中，A表示输入端口，Y表示输出端口。
VCC和GND分别用来提供芯片的电源。
这些引脚通过焊接连接到电路板上，使芯片能够正常工作。
SN7404芯片的工作电压范围为4.75V至5.25V，工作温度范围为0℃至70℃。
它的封装形式有DIP（双列直插）和SOIC （小型外包装），用户可以根据实际需求选择适合的封装形式。
SN7404芯片的内部结构由六个独立的反相器（Inverter）组成。
每个反相器的输入端与对应的输出端相连，形成一个闭环。
当输入端接收到高电平信号（+5V）时，输出端输出低电平信号（0V）；当输入端接收到低电平信号（0V）时，输出端输出高电平信号（+5V）。
这种反相的特性使得SN7404芯片能够对信号进行逆转处理。
在数字逻辑电路中，SN7404芯片经常用于信号的放大、反相和级联处理。
例如，当需要将一个信号进行反相处理时，可以将该信号输入到SN7404芯片的任意一个输入端口，通过芯片内部反相器的处理，就可以得到反相输出信号。
另外，SN7404芯片还可以被级联连接，实现更复杂的逻辑运算。
通过将多个SN7404芯片的输出端口连接到下一个芯片的输入端口，可以实现与门、或门、非门等逻辑电路。
总结起来，7404芯片是一种六通道反相器芯片，用于信号的反相处理和逻辑运算。
它通过六个反相器将输入信号取反，并输出给下一个级联的电路。
在数字逻辑电路中，7404芯片起到了重要的作用，增强了信号处理的灵活性和可扩展性。
