HD74HC138
3-to-8-line Decoder/Demultiplexer with Address Latch
REJ03D0570-0300
Rev.3.00
Mar 25, 2009
Description
The HD74HC138 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
• High Speed Operation: tpd (A, B, C to Y) = 16.5 ns typ (CL = 50 pF)
• High Output Current: Fanout of 10 LSTTL Loads
• Wide Operating Voltage: VCC = 2 V to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
• Ordering Information
