DG467/DG468 Vishay Siliconix Low Power, High Voltage SPST Analog Switches DESCRIPTION FEATURES The DG467 and DG468 are dual supply single-pole/single- • • • • • • • throw (SPST) switches. On resistance is 10 Ω maximum and flatness is 2 Ω max over the specified analog signal range. These analog switches were designed to provide high speed, low error switching of precision analog signals. The primary application areas are in the routing and switching in ± 15 V Analog Signal Range On-Resistance - rDS(on): 10 Ω max Fast Switching Action - TON: 100 ns VL Logic Supply Not Required TTL CMOS Input Compatible Rail To Rail Signal Handling Dual Or Single Supply Operation RoHS COMPLIANT telecommunications and test equipment. Combining low power, low leakages, low on-resistance and small physical BENEFITS size, the DG467/468 are also ideally suited for portable and • • • • • • battery powered industrial and military equipment. The DG467 has one normally closed switch, while the DG468 switch is normally open. They operate either from a single + 7 V to 36 V supply or from dual ± 4.5 V to ± 20 V Wide Dynamic Range Low Signal Errors and Distortion Break-Before-Make Switching Action Simple Interfacing Reduced Board Space Improved Reliability supplies. They are offered in the very popular, small TSOP6 APPLICATIONS package. • • • • • • • • Precision Test Equipment Precision Instrumentation Communications Systems PBX, PABX Systems Audio Equipment Redundant Systems PC Multimedia Boards Hard Disc Drives FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG467 TRUTH TABLE NC 1 6 COM V- 2 5 V+ IN 3 4 GND Logic 0 1 DG467 ON OFF DG468 OFF ON Logic "0" ≤ 0.8 V Logic "1" ≥ 2.4 V Device Marking: DG467DV = G7xxx DG468DV = G8xxx TSOP6 DG468 NO 1 6 COM V- 2 5 V+ IN 3 4 GND TSOP6 Document Number: 74413 S-70327–Rev.
