DESCRIPTION

The 74VHC240 is an advanced high-speed

CMOS

OCTAL

BUS

BUFFER

(3-STATE)

fabricated

with

sub-micron silicon gate and

double-layer metal wiring C2MOS technology.

G output enable governs four BUS BUFFERs.

This device is designed to be used with 3 state

memory address drivers, etc.

Power down protection is provided on all inputs

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.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
