Octal Bus Buffer/Line Driver
Inverting with 3-State Outputs
The MC74VHCT240A 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 MC74VHCT240A is an inverting 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 VHCT240A 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 = 4µA (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: 110 FETs or 27.5 Equivalent Gates
