NC7WB3306
2-Bit Low Power Bus Switch
May 2000
Revised December 2005
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-
ages up to 5.5V independent of V_CC.
