description

The ’HC139 are designed for high-performance
memory-decoding or data-routing applications
requiring very short propagation delay times. In
high-performance memory systems, these
decoders can minimize the effects of system
decoding. When employed with high-speed
memories utilizing a fast enable circuit, the delay
time of these decoders and the enable time of the
memory are usually less than the typical access
time of the memory . This means that the effective
system delay introduced by the decoders is
negligible.

The ’HC139 comprise two individual 2-line to
4-line decoders in a single package. The
active-low enable (G
line in demultiplexing applications. These
decoders/demultiplexers feature fully buffered
inputs, each of which represents only one
normalized load to its driving circuit.
