FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The octal bus switch has standard 245 pinouts. The CBTLV3245 is
designed for asynchronous communication between data buses. When
Output Enable (OE) is low, the 8-bit bus switch is on and port A is connected
to Port B. When OE is high, the switch 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,
OE should be tied to VCC through a pullup resistor.
