KK74HCT138A 1-of-8 Decoder/Demultiplexer

TECHNICAL DATA KK74HCT138A 1-of-8 Decoder/Demultiplexer High-Performance Silicon-Gate CMOS The KK74HCT138A is identical in pinout to the LS/ALS138. The KK74HCT138A may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The KK74HCT138A decodes a three-bit Address to one-of-eight active-lot outputs. This device featur.

Features

three Chip Select inputs, two active-low and one active-high to facilitate the demultiplexing, cascading, and chip-selecting functions. The demultiplexing function is accomplished by using the Address inputs to select the desired device output; one of the Chip Selects is used as a data input while the other Chip Selects are held in their active states.
• TTL/NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA ORDERING INFORMATION KK74HCT138AN Plastic KK74HCT138AD SOIC TA = -55° to 125° C for all p.
