MM74HC139

Dual 2-To-4 Line Decoder

equivalent to the 74LS139. All inputs are protected from

damage due to static discharge by diodes to V_CCand

General Description

The MM74HC139 decoder utilizes advanced silicon-gate

CMOS technology, and is well suited to memory address

decoding or data routing applications. It possesses the

high noise immunity and low power consumption usually

associated with CMOS circuitry, yet has speeds compara-

ble to low power Schottky TTL logic.

ground.

Features

■ Typical propagation delays —

Select to outputs (4 delays): 18 ns

Select to output (5 delays): 28 ns

Enable to output: 20 ns

The MM74HC139 contain two independent one-of-four

decoders each with a single active low enable input (G1, or

G2). Data on the select inputs (A1, and B1 or A2, and B2)

cause one of the four normally high outputs to go LOW.

■ Low power: 40 µW quiescent supply power

■ Fanout of 10 LS-TTL devices

The decoder’s outputs can drive 10 low power Schottky

TTL equivalent loads, and are functionally as well as pin

■ Input current maximum 1 µA, typical 10 pA
