DG721, DG722, DG723 Vishay Siliconix 1.8 V to 5.5 V, 4 Dual SPST Switches FEATURES DESCRIPTION Halogen-free according to IEC 61249-2-21 The DG721, DG722 and DG723 are precision dual SPST definition switches designed to operate from single 1.8 V to 5.5 V 1.8 V to 5.5 V single power supply power supply with low power dissipation. The DG721, Low and flat switch on resistance, 2.5 /typ. DG722 and DG723 can switch both analog and digital Low leakage and parasitic capacitance signals within the power supply rail, and conduct well in both 366 MHz, - 3 dB bandwidth directions. Latch-up current > 300 mA (JESD78) Fabricated with advance submicron CMOS process, these Space saving packages switches provide high precision low and flat ON resistance, 2 mm x 2 mm TDFN8 low leakage current, low parasitic capacitance, and low MSOP8 charge injection. Over voltage tolerant TTL/CMOS compatible The DG721, DG722 and DG723 contain two independent Compliant to RoHS Directive 2002/95/EC Single Pole Single Throw (SPST) switches. Switch-1 and switch-2 are normally open for the DG721 and normally APPLICATIONS closed for the DG722. For the DG723, switch-1 is normally Healthcare and medical devices open and switch-2 is normally closed with a Break-Before- Test instruments Make switching timing. Portable meters The DG721, DG722 and DG723 are the ideal switches for Data acquisitions use in low voltage instruments and healthcare devices, fitting Control and automation the circuits of low voltage ADC and DAC, analog front end PDAs and modems gain control, and signal path control. Communication systems As a committed partner to the community and the Audio, video systems environment, Vishay Siliconix manufactures this product with Mechanical reed relay replacement lead (Pb)-free device termination. The TDFN8 package has a nickel-palladium-gold device termination and is represented by the lead (Pb)-free -E4 suffix to the ordering part number. The MSOP-8 package has tin device termination and is represented by -E3. Both device terminations meet all JEDEC standards for reflow and MSL rating. As a further sign of Vishay Siliconix s commitment, the DG721, DG722 and D723 are fully RoHS compliant and Halogen-free.
