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
VCC = 0 V. These input and output structures help pwrwewv.DeatnaSthedet4eUv.ciocme
destruction caused by supply voltage−input/output voltage mismatch,
battery backup, hot insertion, etc.

6. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.
Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC/2 (per decoder). CPD is used to determine the
no−load dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
