3-to-8 Line Decoder
The TC74HC138A is a high speed CMOS 3-to-8 DECODER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
When the device is enabled, 3 Binary Select inputs (A, B and C) determine which one of the outputs ( Y0 - Y7 ) will go low.
When enable input G1 is held low or either G2A or G2B is held high, decoding function is inhibited and all outputs go high.
G1, G2A , and G2B inputs are provided to ease cascade connection and for use as an address decoder for memory systems.
