DESCRIPTION

The 74VHCT16240A is an advanced high-speed

CMOS

fabricated with sub-micron silicon gate and

double-layer metal wiring C

Any nG output control governs four BUS

BUFFERS. Output Enable inputs (nG) tied

together give full 16 bit operation.

When nG is LOW, the outputs are on. When nG is

HIGH, the output are in high impedance state.

This device is designed to be used with 3 state

memory address drivers, etc.

Power down protection is provided on all inputs

and outputs and 0 to 7V can be accepted on

inputs with no regard to the supply voltage. This

device can be used to interface 5V to 3V since all

inputs are equipped with TTL threshold

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
