MC74HC240ADTR2 Logic - Buffers, Drivers, Receivers, Transceivers by ON Semiconductor

1-of-8 Decoder/DemultiplexerHigh−Performance Silicon−Gate CMOS
The MC74HC238A is identical in pinout to the LS238.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The HC238A decodes a three−bit Address to one−of−eight active−high 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.
