TECHNICAL DATA

1-of-16 Decoder/Demultiplexer

High-Performance Silicon-Gate CMOS

IN74HC154

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.

• 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
