U74HCT138 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD U74HCT138 3-TO-8 LINE DECODERS / DEMULTIPLEXERS - DESCRIPTION CMOS IC The U74HCT138 decodes a three- bit Address to 1- of- 8 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. The demultiplexing function is acplished by using the Address inputs to select the desired device output. One of the Chip Selects is used as a data input while the other Chip Selects are held in their active states. - Features - Operate from 4.5V to 5.5V - Low Input Current:1.0uA Max - Low Power Consumption: 8μA Max - Typical tPD=15ns - Inputs are TTL...
