inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
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.
