The TC7MBD3245FK 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. When output 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 internal diode which adds to power supply line is enable to realize the shift of signal level from 5 V to 3.3 V. All inputs are equipped with protection circuits against static discharge.
