A20552S - MC74HC138ADTR2G SMD 1-of-8 Decoder/Demultiplexer (On Semi)

The MC74HC138ADTR2G is identical in pinout to the LS138. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The MC74HC138ADTR2G decodes a three-bit address to one-of-eight active-low outputs. This device 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.

Features:
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0 mA
High Noise Immunity Characteristic of CMOS Devices
Chip Complexity: 100 FETs or 29 Equivalent Gates
