HD74HCT138 Datasheet | Hitachi Semiconductor

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, G2A and G2B) are provided to ease the cascading of decoders. Features - - - - - - LSTTL Output Logic Level patibility as well as CMOS Output patibility High Speed Operation: tpd (A, B, C to Y) = 18.5 ns typ (CL = 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 =...
