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.
