description/ordering information

The ’AHCT139 devices are dual 2-line to 4-line

decoders/demultiplexers designed for 4.5-V to

5.5-V

operation. These devices are

1 20 19

1Y0

designed to be used in high-performance

memory-decoding or data-routing applications

requiring very short propagation delay times. In

high-performance memory systems, these

decoders can be used to minimize the effects of

system decoding. When used with high-speed

memories utilizing a fast enable circuit, the delay

timesofthesedecodersandtheenabletimeofthe

memory usually are less than the typical access

time of the memory. This means that the effective

system delay introduced by the decoders is

negligible.
