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 completely compatible 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 Speed Termination Effects
