onsemi NLV74HC138ADTR2G

The MC74HC138A has the same pinout as the LS138. The device inputs are compatible with standard CMOS outputs; with pull-up resistors, they are compatible with LSTTL outputs.

The HC138A decodes a 3-bit address into one-of-eight active-low outputs. The device features three chip select inputs — two active-low and one active-high — to facilitate demultiplexing, cascading, and chip select functions. Demultiplexing is accomplished by using the address inputs to select the desired device output; one chip select serves as the data input while the remaining chip selects are held in the active state.
