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 Applications Features z z z z z z z z z z Sample-and-Hold Circuits Battery powered Equipment Audio and Video Signal Routing Communication Circuits z z Pin Configurations Control Inputs Are 5V Tolerant Low Charge Injection Excellent ON-State Resistance Matching Low Total Harmonic Distortion (THD) 1.65V to 5.5V Single-Supply Operation ESD Performance: Human Body Model＞2KV Machine Model＞200V SC70-6/SC88/SOT363 Package Pb-Free Package Top View M: Monthly Code UM3156 SC70-6/SC88/SOT363 ________________________________________________________________________ http://www.union-ic.com Rev.01 Dec.2009 1/9 UM3156 Ordering Information Part Number Packaging Type Marking Code UM3156 SC70-6/SC88/SOT363 U73 Shipping Qty 3000pcs/7 Inch Tape & Reel Function Table Select Input L H Function B0 Connected to A B1 Connected to A Absolute Maximum Ratings Symbol Parameter Limit Unit VCC Supply Voltage - 0.5 to + 6.5 V VS DC Switch Voltage (Note 1) - 0.5 to (VCC + 0.5) VIN DC IN Voltage (Note 1) - 0.5 to + 6.5 -50 IIK DC Input Diode Current@ VIN＜0V mA IOUT DC Output Current 128 ICC/ IGND DC VCC or Ground Current +100 TJ Junction Temperature Under Bias +150 TSTG Storage Temperature - 65 to +150 °C TL Junction Lead Temperature (Soldering, 10seconds) 260 θJA Thermal Resistance 350 °C/W PD Power Dissipation @ +85°C 180 mW 1: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.
