Dual 1-of-8 Decoder/Demultiplexer 74AC138, 74ACT138 General Description The AC138/ACT138 is a high−speed 1−of−8 decoder/demultiplexer. This device is ideally suited for high−speed bipolar memory chip select address decoding. The multiple input enables allow parallel expansion to a 1−of−24 decoder using just three AC138/ACT138 devices or a 1−of−32 decoder using four AC138/ACT138 devices and one inverter Features  ICC Reduced by 50%  Demultiplexing Capability  Multiple Input Enable for Easy Expansion  Active LOW Mutually Exclusive Outputs  Outputs Source/Sink 24 mA  ACT138 Has TTL Compatible Inputs  These are Pb−Free Devices VCC O0 O1 O2 O3 O4 O5 O6 16 15 14 13 12 11 10 9 DATA SHEET www.onsemi.
