SN74AHCT139/SN74AHCT139-Q1 Decoders/Demultiplexers

Texas Instruments SN74AHCT139/SN74AHCT139-Q1 2-to-4-Line Decoders/Demultiplexers are designed for 4.5V to 5.5V VCC operation. These devices are intended for high-performance data routing or memory decoding applications requiring very short propagation delay times. These decoders can be used to minimize the effects of system decoding in high-performance memory systems. When used with high-speed memories utilizing a fast enable circuit, the enable time of the memory and the delay times of these decoders are usually less than the typical access time. This reduction means that the effective system delay introduced by the decoders is negligible.
