Description

Pericom Semiconductor's PI3A114-A is a one-to-four bidirectional multiplier-demultiplier. Specifi ed 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.Functional Block Diagram A Y E SW EN A1 A2 A3 Y SW SW SW SW Pin Confi guration (top view) 10VDD 5 6 NC EN A11 1112 SI GND Y NC Truth Table(1) Enable Select FunctionEN S 1 S0 L X X Y=A x, Hi-Z H L L Y = A 0; A1, A2, A3 = Hi-Z H L H Y = A 1; A0, A2, A3 = Hi-Z H H L Y = A 2; A0, A1, A3 = Hi-Z H H H Y = A 3; A0, A1, A2 = Hi-Z Pin Description Pin Name Description AN Data I/O S0-1 Select Inputs EN Enable Y Data I/O Common GND Ground VDD Power 12-pin TQFN 5 A1 Y 3 4 VDD S1EN GND 10-pin TQFN 08-0231
