2-Bit Low Power Bus Switch

The NC7WB3306 is a 2-bit ultra high-speed CMOS FET bus Switch with TTL-compatible active LOW control inputs. The low On Resistance of the Switch allows inputs to be connected to outputs with minimal propagation delay and without generating additional ground bounce noise. The device is organized as a 2-bit Switch with independent bus enable (OE#) controls. When 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. Control inputs tolerate voltages up to 5.5V independent of VCC.
