NC7WB3125
TinyLogic UHS 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. 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 V_CC.
