Description
Pericom Semiconductor's PI3A114-A is a one-to-four bidirectional multiplier-demultiplier. Specified over a wide operating power supply voltage of 1.8 to 3.3V, the PI3A114-A offer good signal linearity. The PI3A114-A offers low-swing input voltage on the EN, S1 and S0 inputs allowing the device to operate at 3.3V, and pass 3.3V channel data, while being controlled from a 1.8V device.

Notes: 1. "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. 2. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. 3. Control input must be held HIGH or LOW; it must not float.
