MC74HC139A/DMC74HC139A

Dual 1-of-4 Decoder/

Demultiplexer

High–Performance Silicon–Gate CMOS

The MC74HC139A is identical in pinout to the LS139. The device

inputs are compatible with standard CMOS outputs; with pull–up

resistors, they are compatible with LSTTL outputs.

This device consists of two independent 1–of–4 decoders, each of

which decodes a two–bit Address to one–of–four active–low outputs.

Active–low Selects are provided to facilitate the demultiplexing and

cascading functions. The demultiplexing function is accomplished by

using the Address inputs to select the desired device output, and

utilizing the Select as a data input.

•

Output Drive Capability: 10 LSTTL Loads

•

Outputs Directly Interface to CMOS, NMOS and TTL

M74HC139/74HC139 功能:2 线—4 线译码器

M74HC139/74HC139 用于高性能的存贮译码或要求传输延迟时间短的数据传输系统,在高性能存贮器系统中,用这种译码器可以提高译码系统的效率。将快速赋能电路用于高速存贮器时,译码器的延迟时间和存贮器的赋能时间通常小于存贮器的典型存取时间,这就是说由 肖特基钳位的系统译码器所引起的有效系统延迟可以忽

略不计。HC139含有两个单独的2 线—4 线译码器,当赋能输入端G为高电平时,按二进制控制输入码从4 个输出端中译出一个低电平输出。在解调器应用中,低电平有效的赋能输入端用作数据线。
