Description	3-to-8-line Decoder/Demultiplexer with Address Latch
Datasheet	HD74HC237_HitachiSemiconductor.pdf

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.

High Speed Operation: tpd (Data to Y) = 19 ns typ (CL = 50 pF) High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) HD74HC237 Function Table Inputs Enable GL X X L L L L L L L L H G1 X L H H H H H H H H H G2 H X L L L L L L L L L Select C X X L L L L H H H H X B X X L L H H L L H H X A X X L H L H L H L H X Outputs Y0 L L.
