MOTOROLA SEMICONDUCTOR TECHNICAL DATA 1-of-16 Decoder/Demultiplexer High Performance Silicon Gate CMOS The MC54/74HC154 is identical in pinout to the LS154.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
This device, when enabled, selects one of 16 active low outputs.
Two active low Chip Selects are provided to facilitate the chip select, demultiplexing, and cascading functions.
