Octal Bus Buffer/Line Driver
with 3-State Outputs
The MC74VHCT244A is an advanced high speed CMOS octal bus
buffer fabricated with silicon gate CMOS technology. It achieves high
speed operation similar to equivalent Bipolar Schottky TTL while
maintaining CMOS low power dissipation.
The MC74VHCT244A is a noninverting 3–state buffer, and has two
active–low output enables. This device is designed to be used with
3–state memory address drivers, etc.
The VHCT inputs are compatible with TTL levels. This device can
be used as a level converter for interfacing 3.3V to 5.0V, because it has
full 5V CMOS level output swings.
The VHCT244A input and output (when disabled) structures
provide protection when voltages between 0V and 5.5V are applied,
regardless of the supply voltage. These input and output structures
help prevent device destruction caused by supply voltage –
input/output voltage mismatch, battery backup, hot insertion, etc.
High Speed: tPD = 5.6ns (Typ) at VCC = 5V
Low Power Dissipation: ICC = 4A (Max) at TA = 25°C
TTL–Compatible Inputs: VIL = 0.8V; VIH = 2.0V
Power Down Protection Provided on Inputs and Outputs
Balanced Propagation Delays
Designed for 4.5V to 5.5V Operating Range
Low Noise: VOLP = 1.1V (Max)
Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300mA
ESD Performance: HBM > 2000V; Machine Model > 200V
Chip Complexity: 112 FETs or 28 Equivalent Gates
