Product Description

The PI3G612 is a 3-port, 6-channel, 1:2 multiplexer/demultiplexer. It features switched 100 K-Ohm active pull-ups on output ports A and B to prevent disconnected floating signals and thereby reduce system noise and power. The Y port can be connected to either the A or B ports, or alternatively both ports can be isolated, disconnected, or all connected. When the EP pin is low, the pull-up transistors are off. When EP is high, the pull-up transistors are on. If EP is not connected, an internal pull-down will turn the pull-up off. If pullups are not used, EP should be connected to ground. The PI3G612 has a wide operating voltage range, very low power consumption and small packaging suitable for mobile, and handheld equipment.
