3-to-8 Decoder/Demultiplexer

General Description

The VHC138 is an advanced high speed CMOS 3-to-8

decoder/demultiplexer 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.

When the device is enabled, 3 binary select inputs (A

and A

LOW. When enable input E

is held HIGH, decoding function is inhibited and all outputs

go HIGH. E

cade connection and for use as an address decoder for

memory systems. An input protection circuit ensures that

Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

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

back up. This circuit prevents device destruction due to

mismatched supply and input voltages.
