TC7MB3257FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MB3257FK
Quad 1-of-2 Multiplexer/Demultiplexer
The TC7MB3257FK is high-speed CMOS quad 1-2
multiplexer/demultiplexer. The low on resistance 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 鈥淗鈥?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.
