74VHC139
Dual 2-to-4 Decoder/Demultiplexer
General Description
The VHC139 is an advanced high speed CMOS Dual 2-to-
4 Decoder/Demultiplexer fabricated with silicon gate
CMOS technology. It achieves the high speed operation
similar to equivalent Bipolar Schottky TTL while maintain-
ing the CMOS low power dissipation.
The active LOW enable input can be used for gating or it
can be used as a data input for demultiplexing applications.
When the enable input is held HIGH, all four outputs are
fixed at a HIGH logic level independent of the other inputs.
An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery back up. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
Features
s High Speed: tPD = 5.0 ns (typ) at TA = 25°C
s Low power dissipation: ICC = 4 µA (Max.) at TA = 25°C
s High noise immunity: VNIH = VNIL = 28% VCC (Min.)
s Power down protection is provided on all inputs
s Pin and function compatible with 74HC139
