UM3257 Low-Voltage Dual SPDT Analog Switch UM3257 DFN12 3.0×1.6 General Description The UM3257 is dual SPDT analog switch fabricated with silicon gate CMOS technology. It achieves very low propagation delay and RDS(ON) resistances while maintaining CMOS low power dissipation. These make it ideal for portable and battery power applications. The switch conducts signals within power rails equally well in both directions when on, and blocks up to the power supply level when off. Break-before-make is guaranteed. The select pin has over-voltage protection that allows voltages above VCC, up to 6.5V to be present on the pin without damage or disruption of operation of the part, regardless of the operating voltage.
