1-of-8 Decoder/Demultiplexer
High-Performance Silicon-Gate CMOS

The SL 74HC138 is identical in pinout to the LS/ALS138. The device inputs ar e compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.

·  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
