PI3A114-A
Low–Voltage, 4:1 Mux/Demux
with Low-Swing Control Inputs
Features
Description
• CMOS Technology for Analog Applications
• Low-swing control inputs
• Low On-Resistance
PericomSemiconductor'sPI3A114-Aisaone-to-fourbidirectional
multiplier-demultiplier. Specified over a wide operating power
supply voltage of 1.8 to 3.3V, the PI3A114-A offer good signal
linearity.
• Wide V Range: 1.8V to 3.3V
DD
The PI3A114-Aoffers 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.
• Rail-to-Rail Signal Range
• Near zero propagation delay
• Fast Switching Speed
• Ultra-low quiescent power
• High Off Isolation: -95dB @ 100kHz
• Crosstalk Rejection Reduces Signal Distortion:
-90dB @ 100kHz
• Packaging (Pb-free & Green):
–12-contact TQFN (3.0×3.0)
–10-contact TQFN (1.6×1.3)
–12-contact TDFN (3.0×3.5)

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.

2. Typical values are at VDD = 1.8V, TA = 25°C ambient and maximum loading.
3. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
4. Measured by the voltage drop between A and Y pin at indicated current through the switch. On-Resistance is determined by the lower of the
voltages on the two (I,Y) pins.
