MM74HC139
Dual 2-To-4 Line Decoder
Features
■ Typical propagation delays:
– Select to outputs (4 delays): 18ns
– Select to output (5 delays): 28ns
– Enable to output: 20ns
■ Low power: 40W quiescent supply power
■ Fanout of 10 LS-TTL devices
■ Input current maximum 1A, typical 10pA
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 com-
parable to low power Schottky TTL logic.
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.
The decoder's outputs can drive 10 low power Schottky
TTL equivalent loads, and are functionally as well as
pin equivalent to the 74LS139. All inputs are protected
from damage due to static discharge by diodes to VCC
and ground.
Ordering Information
Device also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering number.
