MC74VHCT139A

Dual 2−to−4 Decoder/

Demultiplexer

The MC74VHCT139A 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 devices 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 device output is compatible with TTL−type input thresholds

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

The MC74VHCT139A input structure provides protection when

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

= 0 V. These input and output structures help prevent device
