description

The SN74CBT3245A provides eight bits of high-speed TTL-compatible bus switching in a standard '245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.

The device is organized as one 8-bit switch. When output enable () is low, the switch is on and port A is connected to port B. When is high, the switch is open and a high-impedance state exists between the two ports.

The SN74CBT3245A is characterized for operation from -40°C to 85°C.
