The SN74CBT3345 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 bank with dual output-enable (OE and OE) inputs. When OE is low

or OE is high, the switch is on and port A is connected to port B. When OE is high and OE is low, the switch is

open and a high-impedance state exists between the two ports.

The SN74CBT3345 is characterized for operation from 0°C to 70°C.
