TC7MB3251FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MB3251FK
1-of-8 FET Multiplexer/Demultiplexer
The TC7MB3251FK is high-speed CMOS 1-8
multiplexer/demultiplexer. The low on resistance of the switch
allows connections to be made with minimal propagation delay
time.
This device is 1 to 8 multiplexer/demultiplexer controlled by
the combination of select inputs (S0, S1, S2) and output enable
(OE). The A inputs is connected to the corresponded B1~B8
outputs determined by the combination both the select inputs (S0,
S1, S2) 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.
