FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The CBTLV16245 is a set of 16-bit bus switches. It has standard 16245
pinouts. The device is organized as dual 8-bit low resistance switches with
independent Output Enable (xOE) control inputs. The switches can be
turned on under the control of the LVTTL-compatible Output Enable signals
(xOE) for bidirectional data flow between port A and port B. When xOE 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.
