DESCRIPTION

The CBT3245A 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 CBT3245A device is organized as one 8-bit switch. When

enable (OE) is LOW, the switch is on and port A is connected to

port B. When OE is HIGH, the switch is open and a high-impedance

state exists between the two ports.

The CBT3245A is characterized for operation from -40 to +85

°C.
