Low Voltage Quad 2-Channel Multiplexer with 5 V Tolerant Inputs and Outputs

Designed for use in 3.3-V systems, it achieves high-speed

operation while maintaining the CMOS low power dissipation.

but it could be used to interface to 5-V supply environment for

inputs.

SELECT and ST inputs. When the ST 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.
