DESCRIPTION:
The octal bus switch has standard 244 pinouts. The CBTLV3244 is
designed for asynchronous communication between data buses. Sets of
four switches are controlled by one output Enable (OE). When
OE
is low,
the set of four bus switches is on and port A is connected to port B. When
OE
is high, the set of four bus switches is off and a high impedance exists
between port A and port B.
To ensure the high-impedance state during power up or power down,
both
OEs
should be tied to V
CC
through a pullup resistor.
APPLICATIONS:
鈥?3.3V High Speed Bus Switching and Bus Isolation
