SN74LS138 Datasheet | onsemi

1- of- 8 Decoder/ Demultiplexer The LSTTL/MSI SN74LS138 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 LS138 devices or to a 1-of-32 decoder using four LS138s and one inverter. The LS138 is fabricated with the Schottky barrier diode process for high speed and is pletely patible with all ON Semiconductor TTL families. - Demultiplexing Capability - Multiple Input Enable for Easy Expansion - Typical Power Dissipation of 32 mW - Active Low Mutually Exclusive Outputs - Input Clamp Diodes Limit High...
