描述 Description

1-of-16 Decoder/Demultiplexer High-Performance Silicon-Gate CMOSThe IN74HC154A is identical inpinouttothe 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 IN74HC154A is primarily used for memory address decoding and data routing applications.

•  Outputs Directly Interface to CMOS, NMOS, and TTL
•  Operating Voltage Range:2.0 to6.0 V
•  Low InputCurrent:1.0 µA
•  High Noise Immunity Characteristic of CMOS Devices
