DESCRIPTION/ORDERING INFORMATION

SN74LVC139A

DUAL 2-LINE TO 4-LINE DECODER/DEMULTIPLEXER

SCAS341O – MARCH 1994 – REVISED FEBRUARY 2005

•

Latch-Up Performance Exceeds 250 mA Per

JESD 17

•

Operates From 1.65 V to 3.6 V

•

ESD Protection Exceeds JESD 22

•

Inputs Accept Voltages to 5.5 V

– 2000-V Human-Body Model (A114-A)

•

– 200-V Machine Model (A115-A)

•

– 1000-V Charged-Device Model (C101)

•

The device comprises two individual 2-line to 4-line decoders in a single package. The active-low enable (G)

input can be used as a data line in demultiplexing applications. This decoder/demultiplexer features fully buffered

inputs, each of which represents only one normalized load to its driving circuit.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in

a mixed 3.3-V/5-V system environment.
