The
KK
74HC154A 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
KK
74HC154A is primarily used for memory address decoding
and data routing applications.
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0
