3-to-8 Line Decoder
The TC74VHC138 is an advanced high speed CMOS 3-to-8
DECODER fabricated with silicon gate C2MOS 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, B and
C) determine which one of the outputs (
When enable input G1 is held low or either 2A
high, decoding function is inhibited and all outputs go high.
G1, 2A
, and 2B
G
inputs are provided to ease cascade
connection and for use as an address decoder for memory
systems.
An input protection circuit ensures that 0 to 5.5 V can be
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5 V to 3 V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
