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 accomplished 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 voltage compatible „ ORDERING INFORMATION www.DataSheet.
