TC74VHC138F/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VHC138F, TC74VHC138FK
3-to-8 Line Decoder
The TC74VHC138 is an advanced high speed CMOS 3-to-8 DECODER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL 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.
An input protection circuit ensures that 0 to 5.
