DESCRIPTION
The CBT3245 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 CBT3245 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 CBT3245 is characterized for operation from –40 to 85 C.
