74VHC138
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 (A0, A1
and A2) determine which one of the outputs (O0–O7) will go
LOW. When enable input E3 is held LOW or either E1 or E2
is held HIGH, decoding function is inhibited and all outputs
go HIGH. E3, E1 and E2 inputs are provided to ease cas-
cade connection and for use as an address decoder for
memory systems. An input protection circuit ensures 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
back up. This circuit prevents device destruction due to
mismatched supply and input voltages.
Features
s High Speed: tPD = 5.7ns (typ) at TA = 25°C
s Low power dissipation: ICC = 4 A (max.) at TA = 25°C
s High noise immunity: VNIH = VNIL = 28% VCC (min.)
s Power down protection provided on all inputs
s Pin and function compatible with 74HC138
Ordering Code:
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
