Automotive Catalog 3-Line to 8-Line Decoders/Demultiplexers

The SN74AHCT138Q 3-line to 8-line

decoder/demultiplexer is designed to be used in high-performance memory-decoding and

data-routing applications that require very short propagation-delay times. In

high-performance memory systems, this decoder can be used to minimize the effects of

system decoding. When employed with high-speed memories utilizing a fast enable

circuit, the delay times of this decoder and the enable time of the memory usually

are less than the typical access time of the memory. This means that the effective

system delay introduced by the decoder is negligible.
