3-Line To 8-Line Decoder / Demultiplexer

The SN74AHCT138 3-line to 8-line decoders/demultiplexers are 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.
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.
