The MC74VHC139 is an advanced high speed CMOS 2–to–4 decoder/
demultiplexer fabricated with silicon gate CMOS technology. It achieves high
speed operation similar to equivalent Bipolar Schottky TTL while maintaining
CMOS low power dissipation.
When the device is enabled (E = low), it can be used for gating or as a data
input for demultiplexing operations. When the enable input is held high, all
four outputs are fixed high, independent of other inputs.
The internal circuit is composed of three stages, including a buffer output
which provides high noise immunity and stable output. The inputs tolerate
voltages up to 7V, allowing the interface of 5V systems to 3V systems.
High Speed: tPD = 5.0ns (Typ) at VCC = 5V
Low Power Dissipation: ICC = 4
μΑ
(Max) at TA = 25
