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 dissipation. The VHC153 is a high-speed Dual
4-Input Multiplexer with common select inputs and indi-
vidual 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 operation, the VHC153 can act as a func-
tion generator and generate 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 prevents device destruction due to
mismatched supply and input voltages.
