2:1 Mux/Demux Bus Switch Features CMOS Technology for Bus and Analog Applications Low On-Resistance: 8Ω at 3.0 Wide Range: 1.65 to 5.5 Rail-to-Rail Signal Range Control Input Overvoltage Tolerance: 5.5(Min) Fast Transition Speed: 2ns at 5.0 High Off Isolation: -63dB @ 10MHz Break-Before-Make Switching High Bandwidth: 350MHz Extended Industrial Temperature Range: -40 C to 85 C Packaging (Lead Free & Green): -12-pin TDFN, 3mm 1mm Pin Assignment 12-pin TDFN DD Description The PI5A3158B is a dual high-bandwidth, fast singlepole 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, 1.65 to 5.5, the PI5A3158B has a maximum ON resistance of 12-ohms at 1.65, 9-ohms at 2.3 & 6-ohms at 4.5. 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.
