HD74HCT238
3-to-8-line Decoder/Demultiplexer
Description
The HD74HCT238 has 3 binary select inputs (A, B, and C). If the device is enabled these inputs
determined which one of the eight normally high outputs will go low. Two active low and one active high
enables (G
1
, G
2A
and G
2B
) are provided to ease the cascading of decoders.
