MC74LCX244 低电压三态非反转八路缓冲器说明书

MC74LCX244Octal Buffer, Non-Inverting, Low Voltage, 3-StateThe MC74LCX244 is a high performance, non−inverting octal buffer operating from a 2.3 to 5.5 V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A V I specification of 5.5 V allows MC74LCX244 inputs to be safely driven from 5 V devices. The MC74LCX244 is suitable for memory address driving and all TTL level bus oriented transceiver applications.Current drive capability is 24 mA at the outputs. The Output Enable (OE) input, when HIGH, disables the output by placing them in a HIGH Z condition.Features•Designed for 2.3 to 5.5 V V CC Operation•5 V Tolerant − Interface Capability With 5 V TTL Logic •Supports Live Insertion and Withdrawal•I OFF Specification Guarantees High Impedance When V CC = 0 V •LVTTL Compatible•LVCMOS Compatible•24 mA Balanced Output Sink and Source Capability•Near Zero Static Supply Current in All Three Logic States (10 m A) Substantially Reduces System Power Requirements •Latchup Performance Exceeds 500 mA•ESD Performance:♦Human Body Model >2000 V♦Machine Model >200 V•NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable•These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant120MARKING DIAGRAMSA=Assembly LocationL, WL=Wafer LotY, YY=YearW, WW=Work WeekG or G=Pb−Free PackageSOIC−20 WBDW SUFFIXCASE 751DLCX244AWLYYWWGLCX244ALYW GGTSSOP−20DT SUFFIXCASE 948E201See detailed ordering and shipping information in the package dimensions section on page 6 of this data sheet.ORDERING INFORMATION(Note: Microdot may be in either location)QFN20MN SUFFIXCASES 485AA& 485CBLCX244ALYW GGSOIC−20 WBTSSOP−20QFN20 − 485AA QFN20 − 485CB244ALYW GGFigure 1.

© 2001 Fairchild Semiconductor Corporation DS500696November 2001Revised November 200174ALVC162244 Low Voltage 16-Bit Buffer/Line Driver with 3.6V Tolerant Inputs and Outputs and 26Ω Series Resistor in Outputs74ALVC162244Low Voltage 16-Bit Buffer/Line Driver with 3.6V Tolerant Inputs and Outputs and 26Ω Series Resistor in OutputsGeneral DescriptionThe ALVC162244 contains sixteen non-inverting buffers with 3-STATE outputs to be employed as a memory and address driver, clock driver, or bus oriented transmitter/receiver. The device is nibble (4-bit) controlled. Each nibble has separate 3-STATE control inputs which can be shorted together for full 16-bit operation.The 74ALVC162244 is designed for low voltage (1.65V to 3.6V) V CC applications with I/O capability up to 3.6V. The 74ALVC162244 is also designed with 26Ω series resistors in the outputs. This design reduces line noise in applica-tions such as memory address drivers, clock drivers, and bus transceivers/transmitters.The 74ALVC162244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain-ing low CMOS power dissipation.Featuress 1.65V to 3.6V V CC supply operation s 3.6V tolerant inputs and outputs s 26Ω series resistors in outputs s t PD3.8 ns max for 3.0V to 3.6V V CC4.3 ns max for 2.3V to 2.7V V CC 7.6 ns max for 1.65V to 1.95V V CCs Power-off high impedance inputs and outputs s Supports live insertion and withdrawal s Uses patented noise/EMI reduction circuitry s Latchup conforms to JEDEC JED78s ESD performance:Human body model > 2000V Machine model > 200Vs Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA)Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to V CC through a pull-up resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.Ordering Code:Note 2: BGA package available in Tape and Reel only.Note 3: Devices also available in Tape and Reel.

The device is nibble (4 bits) con-trolled with each nibble functioning identically, but indepen-dent of each other. The control pins may be shorted together to obtain full 16-bit operation.The 3-STATE out-puts are controlled by an Output Enable (OE n ) input. When OE n is LOW, the outputs are in the 2-state mode. When OE n is HIGH, the standard outputs are in the high imped-ance mode but this does not interfere with entering new data into the inputs.Logic Diagram 474A L V C 162244Absolute Maximum Ratings (Note 4)Recommended Operating Conditions (Note 6)Note 4: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Rat-ings.
