Additional preview pages of the HD74HCT237 datasheet.

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.

LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility High Speed Operation: tpd (A, B, C to Y) = 23 ns typ (C L = 50 pF) High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 4.5 to 5.5 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) HD74HCT237 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.
