PI3A114-A
Low–Voltage, 4:1 Mux/Demux
with Low-Swing Control Inputs
Description
Pericom Semiconductor's PI3A114-Ais 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.
