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.
APPLICATIONS:
3.3V High Speed Bus Switching and Bus Isolation
