DG9424, DG9425, DG9426 Vishay Siliconix Low-Voltage, Dual Supply, Low RON, Quad SPST Analog Switches DESCRIPTION FEATURES The DG9424, DG9425, DG9426 are low voltage precision monolithic quad single-pole-single-throw analog switches. • 2.7 V thru 12 V single supply or ± 3 thru ± 6 dual supply • On-resistance - RDS(on): 1.7 Ω • Fast switching - tON: 42 ns - tOFF: 28 ns • TTL, CMOS compatible • Low leakage: 0.2 nA • 2000 V ESD protection Using BiCMOS wafer fabrication technology allows the DG9424, DG9425, DG9426 to operate on single and dual supplies. Single supply voltage ranges from 3 to 12 V while dual supply operation is recommended with ± 3 to ± 6 V. Combining high speed (tON: 42 ns), flat RDS(on) over the analog signal range (Ω), minimal insertion lose (- 3 dB at 190 MHz), and excellent crosstalk and off-isolation performance, the DG9424, DG9425, DG9426 are ideally suited for audio and video signal switching. The DG9424 and DG9425 respond to opposite control logic as shown in the Truth Table. The DG9426 has two normally open and two normally closed switches. BENEFITS • • • • Widest dynamic range Low signal errors and distortion Break-before-make switching action Simple interfacing APPLICATIONS • • • • • • Automatic test equipment Data acquisition systems Communication systems ADC systems xDSL and PBX/PABX Audio signal routing FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG9424/DG9425 TSSOP IN1 1 16 IN2 COM1 2 15 COM2 NC1/NO1 3 14 NC2/NO2 V- 4 13 V+ GND 5 12 VL NC4/NO4 6 11 NC3/NO3 COM4 7 10 COM3 IN4 8 9 IN3 TRUTH TABLE Logic DG9424 0 OFF DG9425 ON 1 ON OFF Top View Document Number: 71807 S09-1675-Rev.
