CD74HC138 data sheet, product information and support | TI.com
TI’s CD74HC138 is a High Speed CMOS Logic 3-to-8 Line Decoder Demultiplexer Inverting and Non-Inverting. Find parameters, ordering and quality information.
The 74HC138; 74HCT138 decodes three binary weighted address inputs (A0, A1 and A2) to eight mutually exclusive outputs (Y0 to Y7). The device features three enable inputs (E1, E2 and E3). Every output will be HIGH unless E1 and E2 are LOW and E3 is HIGH.

SNx4HC138 3-Line To 8-Line Decoders/Demultiplexers
The SNx4HC138 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 …
The CDx4HC(T)138 and '238 are three to eight decoders with one standard output strobe (G2) and two active low output strobes (G 1 and G 0). When the outputs are gated by any of the strobe inputs, they are all forced into the high state.
The HC138 decodes a three−bit Address to one−of−eight active−low outputs. This device features three Chip Select inputs, two active−low and one active−high to facilitate the demultiplexing, cascading, and chip−selecting functions.
