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.
