Quad 2-Channel Multiplexer
The TC74LVX157F/ FT is a high-speed CMOS quad 2-channel
multiplexer fabricated with silicon gate CMOS technology.
Designed for use in 3-V systems, it achieves high-speed operation
while maintaining the CMOS low power dissipation.
This device is suitable for low-voltage and battery operated
systems.
This device consist 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 V can be applied
to the input pins without regard to the supply voltage. This
device can be used to interface 5V to 3V systems and two supply
systems such as battery back up. This circuit prevents device
destruction due to mismatched supply and input voltages.
