NC7WB3125 - 2-Bit Low Power Bus Switch

General Description

The NC7WB3125 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.

NC7WB3125 2-Bit Low Power Bus Switch NC7WB3125 2-Bit Low Power Bus Switch May 2000 Revised December 2005 General Description The NC7WB3125 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 2bit 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.
