FUNCTIONAL BLOCK DIAGRAM

LOW-VOLTAGE 16-BIT

BUS SWITCH

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

turnedonunderthecontroloftheLVTTL-compatibleOutputEnablesignals

(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,
