    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, one of 16 active-low outputs. Two active-low Chip s are provided to facilitate the chip, demultiplexing, and cascading functions. When either Chip is high, all outputs are high. The demultiplexing function is accomplished by using the Address inputs to the desired device  output.
The IN74HC154 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 μA
• High Noise Immunity Characteristic of CMOS Devices
