The TC7MB3257C is a Low Capacitance CMOS Quad 1-of-2

multiplexer/demultiplexer. The low on resistance and the low

capacitance of the switch allows connections to be made with

minimal propagation delay time.

This device consists of four individual two-inputs

multiplexer/demultiplexer with common select input (S) and

output enable ( OE ). The A inputs is connected to the B1 or B2

outputs determined by the combination both the select input (S)

and output enable ( OE ). When the output enable ( OE ) input is

held “H” level, the switches are open with regardless the state of

select inputs and a high-impedance state exists between the

switches.

All inputs are equipped with protection circuits against static

discharge.
