Features

Description

• Multifunction Capability

The CD74HC139 and CD74HCT139 devices contain two

independent binary to one of four decoders each with a

single active low enable input (1E or 2E). Data on the select

inputs (1A0 and 1A1 or 2A0 and 2A1) cause one of the four

normally high outputs to go low.

- Binary to 1 of 4 Decoders or 1 to 4 Line

Demultiplexer

• Active Low Mutually Exclusive Outputs

• Fanout (Over Temperature Range)

If the enable input is high all four outputs remain high. For

demultiplexer operation the enable input is the data input.

The enable input also functions as a chip select when these

devices are cascaded. This device is functionally the same

as the CD4556B and is pin compatible with it.

- Standard Outputs. . . . . . . . . . . . . . . 10 LSTTL Loads

- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads

• Wide Operating Temperature Range . . . -55 C to 125 C

• Balanced Propagation Delay and Transition Times

The outputs of these devices can drive 10 low power

Schottky TTL equivalent loads. The 74HCT logic family is

functionally as well as pin equivalent to the 74LS logic family.
