description/ordering information
The ’AHC138 decoders/demultiplexers are designed for high-performance memory-decoding and data-routing
applications that require very short propagation-delay times. In high-performance memory systems, these
decoders 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 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.

description/ordering information (continued)
The conditions at the binary-select inputs and the three enable inputs select one of eight output lines. Two
active-low and one active-high enable inputs reduce the need for external gates or inverters when expanding.
A 24-line decoder can be implemented without external inverters, and a 32-line decoder requires only one
inverter. An enable input can be used as a data input for demultiplexing applications.
