TC74VHC157F/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VHC157F, TC74VHC157FK
Quad 2-Channel Multiplexer
The TC74VHC157 is an advanced high speed CMOS QUAD 2CHANNEL MULTIPLEXER 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.
It consists of four 2-input digital multiplexers with common select and strobe inputs.
When the STROBE input is held “H” level, selection of data is inhibited and all the outputs become “L” level.
The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs.
An Input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage.
