NC7WB3306

2-Bit Low Power Bus Switch

General Description

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 volt-
