SN74HC139-Q1 Datasheet (Texas Instruments) - DUAL 2-LINE TO 4-LINE DECODER/DEMULTIPLEXER

SN74HC139-Q1, DUAL 2-LINE TO 4-LINE DECODER/DEMULTIPLEXER

ordering information The SN74HC139 device is designed for high-performance memory-decoding or data-routing applications requiring very short propagation delay times.

In high-performance memory systems, this decoder can minimize the effects of system decoding.

When employed with high-speed memories u
