description
The ’AHCT139 devices are dual 2-line to 4-line
decoders/demultiplexers designed for 4.5-V to
5.5-V
VCC operation. These devices are
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 times of these decoders 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 decoders is negligible.
The active-low enable (G) input can be used as a data line in demultiplexing applications. These
decoders/demultiplexers feature fully buffered inputs, each of which represents only one normalized load to its
driving circuit.
The SN54AHCT139 is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74AHCT139 is characterized for operation from –40
°C to 85°C.
