Description	3-to-8-line Decoder/Demultiplexer with Address Latch
Datasheet	HD74HCT237_HitachiSemiconductor.pdf

The HD74HCT237 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.
