1 / 11 page © Semiconductor Components Industries, LLC, 2006 March, 2006 − Rev. 6 1 Publication Order Number: MC74AC138/D 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−32decoder 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 w These 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.
