3-to-8-line Decoder/Demultiplexer

Description The HD74HCT138 has 3 binary select inputs (A, B, and C). If the device is enabled these inputs determine which one of the eight normally high outputs will go low. Two active low and one active high enables (G1, G2Aand G2B) are provided to ease the cascading of decoders. Fe
