MC74AC138, MC74ACT138 1−of−8 Decoder/Demultiplexer The MC74AC138/74ACT138 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 MC74AC138/74ACT138 devices or a 1−of−32 decoder using four MC74AC138/74ACT138 devices and one inverter.
- Demultiplexing Capability
- Multiple Input Enable for Easy Expansion
- Active LOW Mutually Exclusive Outputs
- Outputs Source/Sink 24 mA
- ′ACT138 Has TTL Compatible Inputs /C0119These devices are available in Pb−free package(s). Specifications herein apply to both standard and Pb−free devices. Please see our website at www.onsemi.com for specific Pb−free orderable part numbers, or contact your local ON Semiconductor sales office or representative.
