The TC7WBL125AFK provides two bits of low-voltage, high-speed bus switching. The low ON-resistance of the switch allows connections to be made with minimal propagation delay and while maintaining CMOS low power dissipation. The device comprises dual 2-bit switches with separate bus enable ( OE ) signals. When OE is low, the switch is on and port A is connected to port B. When OE is high, the switch is off and a high-impedance state exists between the two ports. All inputs are equipped with protection circuits to guard against static discharge.
