SIMPLIFIED SCHEMATIC, EACH SWITCH
DESCRIPTION:
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.
both OEs should be tied to V
The octal bus switch has standard 244 pinouts. The CBTLV3244 is
