Description

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. SN74LS138 Features • 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
