DG2537, DG2538, DG2539 Vishay Siliconix 4 Dual SPST Switches DESCRIPTION FEATURES The DG2537, DG2538, and DG2539 are low voltage, precision dual SPST switches that can be operated in a single supply or in a dual supply configuration power supply with low power dissipation. The DG2537, DG2538 and DG2539 can switch both analog and digital signals within the power supply rail, and conduct well in both directions. Fabricated with advance submicron CMOS process, these switches provide high precision low and flat ON resistance, low leakage current, low parasitic capacitance, and low charge injection. The DG2537, DG2538 and DG2539 contain two independent Single Pole Single Throw (SPST) switches. Switch-1 and switch-2 are normally open for the DG2537 and normally closed for the DG2538. For the DG2539, switch-1 is normally open and switch-2 is normally closed with a Break-Before-Make switching timing. The DG2537, DG2538 and DG2539 are the ideal switches for use in low voltage instruments and healthcare devices, fitting the circuits of low voltage ADC and DAC, analog front end gain control, and signal path control. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with lead (Pb)-free device termination. As a further sign of Vishay Siliconix's commitment, the DG2537, DG2538 and D2539 are fully RoHS compliant and halogen-free. • Halogen-free According to IEC 61249-2-21 Definition • Low and flat switch on resistance, 2.5 /typ • Low leakage and parasitic capacitance • 366 MHz, - 3 dB bandwidth • Latch-up current > 300 mA (JESD78) • Over voltage tolerant TTL/CMOS compatible • Compliant to RoHS Directive 2002/95/EC APPLICATIONS • • • • • • • • • Healthcare and medical devices Test instruments Portable meters Data acquisitions Control and automation PDAs and modems Communication systems Audio, video systems Mechanical reed relay replacement FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG2537, MSOP-10 DG2539, MSOP-10 DG2538, MSOP-10 NO1 1 10 V+ NC1 COM1 2 9 IN1 COM1 2 9 IN2 3 8 COM2 IN2 3 8 COM2 GND 4 7 NO2 GND 4 7 NC2 V- 5 6 V- 5 6 1 Top View NO1 1 10 V+ IN1 COM1 2 9 IN1 IN2 3 8 COM2 GND 4 7 NC2 V- 5 6 Top View Top View TRUTH TABLE (DG2537, DG2538) Logic 10 V+ TRUTH TABLE (DG2539) DG2537 DG2538 Switches Logic Switch-1 Switch-2 0 1 Off 0 Off On 1 0 On 1 On Off ORDERING INFORMATION Temperature Range - 40 °C to 85 °C Document Number: 63370 S11-1551-Rev.
