US5C3306
Preliminary
2-BIT BUS SWITCH WITH
ACTIVE LOW ENABLES
DESCRIPTION
The UTC US5C3306 consist of two independent 5Ω switches
with fast individual enables. The “A” pin is connected to the “B” pin
directly when the associated Bus Enable (BE) pin is set to “Low”.
The bus switch introduces no additional propagation delay or
additional ground bounce noise.
FEATURES
* Low on-resistor between two ports (5Ω typical)
* Near-Zero propagation delay
* Direct bus connection when switches are ON
* Ultra Low Quiescent Power (0.2μA typical)
- Ideally suited for notebook applications
