Low Voltage Dual SPDT Analog Switch 2:1 Mux/Demux Bus Switch
Features
Description
CMOS Technology for Bus and Analog
The PI5A3158B is a dual high-bandwidth, fast single-
pole double-throw (SPDT) CMOS switch. It can be used
as an analog switch or as a low-delay bus switch.
Specified over a wide operating power supply voltage
range, 1.65V to 5.5V, the PI5A3158B has a maximum
ON resistance of 12-ohms at 1.65V, 9-ohms at 2.3V &
6-ohms at 4.5V.
Applications
Low On-Resistance: 8Ω at 3.0V
Wide VCC Range: 1.65V to 5.5V
Rail-to-Rail Signal Range
Control Input Overvoltage Tolerance: 5.5V(Min)
Fast Transition Speed: 2ns at 5.0V
High Off Isolation: -63dB @ 10MHz
Break-Before-Make Switching
High Bandwidth: 350MHz
Break-before-make switching prevents both switches
being enabled simultaneously. This eliminates signal
disruption during switching.
The control input, S, is independent of supply voltage.
Extended Industrial Temperature Range:
-40°C to 85°C
