TC7MB3257FK_07

Manufacturer Part Number
TC7MB3257FK_07
Description
Quad 1-of-2 Multiplexer/Demultiplexer
Manufacturer
TOSHIBA [Toshiba Semiconductor]
Datasheet
Quad 1-of-2 Multiplexer/Demultiplexer
multiplexer/demultiplexer. The low on resistance of the switch
allows connections to be made with minimal propagation delay
time.
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.
