MC74VHCT139A
Description
Dual 2-to-4 Decoder/ Demultiplexer
Manufacturer
ON Semiconductor
Datasheet
MC74VHCT139A
Dual 2−to−4 Decoder/
Demultiplexer
decoder/demultiplexer fabricated with silicon gate CMOS technology.
It achieves high speed operation similar to equivalent Bipolar
Schottky TTL devices while maintaining CMOS low power
dissipation.
a data input for demultiplexing operations. When the enable input is
held high, all four outputs are fixed high, independent of other inputs.
output which provides high noise immunity and stable output.
and the output has a full 5.0 V CMOS level output swing. The input
protection circuitry on this device allows overvoltage tolerance on the
input, allowing the device to be used as a logic−level translator from
3.0 V CMOS logic to 5.0 V CMOS logic, or from 1.8 V CMOS logic
to 3.0 V CMOS logic while operating at the high−voltage power
supply
voltages up to 7.0 V are applied, regardless of the supply voltage. This
allows the MC74VHCT139A to be used to interface 5.0 V circuits to
3.0 V circuits. The output structures also provide protection when
