TOSHIBA TC7WB383FK

TC7WB383FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7WB383FK
2-Bit Bus Exchange Switch
The TC7WB383FK is a low on-resistance, high-speed CMOS
2-bit bus exchange switch. This bus switch allows the connections
or disconnections to be made with minimal propagation delay
while maintaining Low power dissipation which is the feature of
CMOS.
When output enable (OE) is at high level, the switches are off.
When at low level, the switches are on, and by the logic of EX
terminal, It can choose whether 2 bits data are transferred to the
corresponding terminal as it is, or the data are transferred to a
terminal with exchanging data line. Therefore it may be used as
2 to 1 multiplexer switch.
Since the switch channels consist of N type MOSFET, the high
level output voltage is provided about 1 V lower than VCC level.
All inputs are equipped with protection circuits to protect the
device from static discharge.

Note 3: This parameter is guaranteed by design but is not tested. The bus switch contributes no propagation delay
other than the RC delay of the typical on resistance of the switch and the 50 pF load capacitance, when
driven by an ideal voltage the source (zero output impedance).
