Overview
Description
The 74CBTLV3244 octal bus switch has standard 244 pinouts and is 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. The 74CBTLV3244 operates at -40 °C to +85 °C.
