MC74HC138A
1of8 Decoder/
Demultiplexer
HighPerformance SiliconGate CMOS
The MC74HC138A 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 HC138A decodes a threebit Address to oneofeight
activelow outputs. This device features three Chip Select inputs, two
activelow and one activehigh to facilitate the demultiplexing,
cascading, and chipselecting 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
