74LCX138MTCX Datasheet PDF - Fairchild

The 74LCX138MTCX is a 1-of-8 Decoder/Demultiplexer with 5V tolerant inputs. This low voltage high-speed device is ideally suited for high-speed memory chip select address decoding. The multiple input enables allow parallel expansion to a 1-of-24 decoder using just three LCX138 devices or a 1-of-32 decoder using four LCX138 devices and one inverter. The 74LCX138 is fabricated with advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
