8-Bit FET Bus Switch
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 the high-impedance state exists between the two ports.
