UM3156
Low-Voltage SPDT Analog Switch
UM3156 SC70-6/SC88/SOT363
General Description
The UM3156 is an advanced CMOS 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.
The UM3156 can maintain low power consumption for rail-to-rail signaling as long as the control
signal input is held at a level that is greater than VIH minimum and less than VIL maximum by
improving the control circuitry input buffer. so the part can be used in mixed voltage rail
environments, especially services the mobile handset applications very well allowing for the direct
interface with baseband processor general purpose I/Os, and it is no longer necessary to have the
control input equal to VCC to maintain low power consumption

Note 3: Measured by the voltage drop between A and B pins at the indicated current through the switch. On
Resistance is determined by the lower of the voltages on the two (A or B Ports).
Note 4: Parameter is characterized but not tested in production.
Note 5: ΔRON = ︱RON (B0) − RON(B1) ︱measured at identical VCC, temperature and voltage levels.
Note 6: Flatness is defined as the difference between the maximum and minimum value of On Resistance
over the specified range of conditions.
Note 7: Guaranteed by design.
Note 8: Guaranteed by design.
Note 9: This parameter is guaranteed by design but not tested. The bus switch contributes no propagation
delay other than the RC delay of the On Resistance of the switch and the 50 pF load capacitance,
when driven by an ideal voltage source (zero output impedance).
Note 10: Off Isolation = 20 log10 [VA/VBn].
Note 11: TA = +25, f = 1 MHz, Capacitance is characterized but not tested in production.
