RS2105XN

RS2105 Ultra Low ON-Resistance, Low Voltage, Dual, SPDT Analog Switch FEATURES DESCRIPTION • -3dB Bandwidth: 30MHz • High Speed, Typically 50ns • Supply Range: +1.8V to +5.5V • Low ON-State Resistance, 0.6Ω(TYP) • Break-Before-Make Switching The RS2105 is a dual, low on-resistance, single-pole double-throw (SPDT) analog switch that is designed to operate from1.8 V to 5.5 V. The RS2105 device can handle both analog and digital signals. It features fast switching speeds (50ns) and • Rail-to-Rail Operation low on-resistance (0.6Ω TYP). • TTL/CMOS Compatible • Extended Industrial Temperature Range: -40°C to +125°C Applications include signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for analog-to-digital and digital-to-analog conversion systems. APPLICATIONS • Wearable Devices • Battery-Operated Equipment • Signal Gating, Chopping, Modulation or Demodulation (Modem) • Portable Computing • Cell Phones PIN CONFIGURATIONS RS2105 FUNCTION TABLE LOGIC 0 1 NO OFF ON V+ 1 10 NO2 NO1 2 9 COM2 COM1 3 8 IN2 IN1 4 7 NC2 NC1 5 6 GND NC ON OFF MSOP-10 RS2105 PIN DESCRIPTION NAME PIN V+ NO1, NO2 1 2, 10 Power Supply Normally-Open Terminal COM1 COM2 3, 9 Common Terminal IN1, IN2 NC1, NC2 GND 4, 8 5, 7 6 Digital Control Pin Normally-Closed Terminal Ground REV C.2 FUNCTION V+ 1 10 NO2 NO1 2 9 COM2 COM1 3 8 IN2 IN1 4 7 NC2 NC1 5 6 GND TDFN-3x3-10L 1 www.run-ic.com RS2105 ABSOLUTE MAXIMUM RATINGS (1) V+, IN to GND..................................................-0.3V to 6.0V Analog, Digital Voltage Range (2) …......– 0.3 to (V+) + 0.3V Continuous Current NO, NC, or COM……......…... ±500mA Peak Current NO, NC, or COM……........….....…... ±800mA Storage Temperature ……….…………… −65°C to +150°C Operating Temperature ……….…….…… −40°C to +125°C Junction Temperature................................................150°C Package Thermal Resistance @ TA = +25°C MSOP-10……….………………………………….... 204°C/W TDFN-3x3-10L………….……….………...……….…40°C/W Lead Temperature (Soldering, 10s) ……………........260°C ESD Susceptibility HBM …......................................................................1000V MM ……………………….........………………...……….300V ESD SENSITIVITY CAUTION ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3V beyond the supply rails should be current-limited to 10mA or less.
