TECHNICAL DATA
IN74HC154
1-of-16 Decoder/Demultiplexer
High-Performance Silicon-Gate CMOS
The IN74HC154 is identical in pinout to the LS/ALS154. The
device inputs are compatible with standard CMOS outputs; with
pullup resistors, they are compatible with LS/ALSTTL 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. When either Chip
Select is high, all outputs are high. The demultiplexing function is
accomplished by using the Address inputs to select the desired device
output.
The IN74HC154 is primarily used for memory address decoding
and data routing applications.
