DG271MIL Vishay Siliconix High-Speed Quad Monolithic SPST CMOS Analog Switch Fast Settling Times Reduced Switching Glitches High Precision Fast Switching tON: 55 ns Low Charge Injection: 5 pC Low rDS(on): 32 TTL/CMOS Compatible Low Leakage: 50 pA High-Speed Switching Sample/Hold Digital Filters Op Amp Gain Switching Flight Control Systems Automatic Test Equipment Choppers Communication Systems The DG271 high speed quad single-pole single-throw analog switch is intended for applications that require low on-resistance, low leakage currents, and fast switching speeds. The military version of the DG271 is manufactured using the Vishay Siliconix high voltage metal gate wafer fabrication process. The military version of the DG271 shares the same performance of the commercial DG271B, which uses the high voltage silicon gate process.
