HD74HC237
3-to-8-line Decoder/Demultiplexer with Address Latch
Description
The HD74HC237 decodes a three-bit Address to one-of-eight active-high outputs. The device has a
transparent latch for storage of the Address. Two Chip Selects, one active-low and one active-high, are
provided 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, and then by using one of the Chip Selects as a data input while holding the other one active.
The HD74HD237 is the noninverting version of the HD74HC137.
