DG9424 DG9424, DG9425 DG9425, DG9426 DG9426 Vishay Siliconix Low-Voltage, Dual Supply, Low RON, Quad SPST Analog Switches DESCRIPTION FEATURES The DG9424 DG9424, DG9425 DG9425, DG9426 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 · 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 DG9424, DG9425 DG9425, DG9426 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 (), minimal insertion lose (- 3 dB at 190 MHz), and excellent crosstalk and off-isolation performance, the DG9424 DG9424, DG9425 DG9425, DG9426 DG9426 are ideally suited for audio and video signal switching. The DG9424 DG9424 and DG9425 DG9425 respond to opposite control logic as shown in the Truth Table. The DG9426 DG9426 has two normally open and two normally closed switches.

Leakage parameters are guaranteed by worst case test conditions and not subject to production test. b. Room = 25 °C, Full = as determined by the operating temperature suffix. c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet. e. Guaranteed by design, not subject to production test. f. VIN = input voltage to perform proper function. Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. www.vishay.com 6 Document Number: 71807 S09-1675-Rev.
