          The 74HC138 is identical in pinout to the LS138. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL  outputs. 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. 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.
