74VHC153

Dual 4-Input Multiplexer

General Description

The VHC153 is an advanced high-speed CMOS device

fabricated with silicon gate CMOS technology. It achieves

the high-speed operation similar to equivalent Bipolar

Schottky TTL while maintaining the CMOS low power dissi-

pation. The VHC153 is a high-speed Dual 4-Input Multi-

plexer with common select inputs and individual enable

inputs for each section. It can select two lines of data from

four sources. The two buffered outputs present data in the

true (non-inverted) form. In addition to multiplexer opera-

tion, the VHC153 can act as a function generator and gen-

erate any two functions of three variables. An input

protection circuit insures that 0V to 7V can be applied to

the input pins without regard to the supply voltage. This

device can be used to interface 5V to 3V systems and two

supply systems such as battery backup. This circuit pre-

vents device destruction due to mismatched supply and

input voltages.
