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.
