SPST Wide Bandwidth Analog Switch
Features
 CMOS Technology for Bus and Analog
Applications
 Low On-Resistance: 8Ω at 3.0V
 Wide V_CC Range: 1.65V to 6.0V
 Rail-to-Rail Signal Range
 Control Input Overvoltage Tolerance: 6.0V
 Fast Transition Speed: 2ns at 5.0V
Description
The PI3A125B is a single-pole single throw (SPST)
normally close (NC) CMOS switch. The switch is open
when IN is HIGH. The high-precision device is ideal for
low-distortion audio, video, signal switching and routing.
Specified over a wide operating power supply voltage,
1.65V to 6.0V, the PI3A125B has on-resistance of 12-
ohms at 1.65V, 9-ohms at 2.3V & 6-ohms at 4.5V.
 High Off Isolation: -63dB @ 10MHz
 Break-Before-Make Switching
The control input, IN, is independent of supply voltage.
 I/O Pins have Power-off Protection Functions
 Extended Industrial Temperature Range:
Pin Assignment
-40°C to 85°C
 Packaging (Pb-free & Green):
PI3A125B SOT23-5/SC70-5
