DG9431 General Description
The DG9431 is a single-pole/double-throw monolithic CMOS analog device designed for high performance switching of analog signals. Combining low power, high speed (tON: 35 ns, tOFF: 20 ns), low on-resistance (rDS(on): 20) and small physical size (TSOP-6), the DG9431 is ideal for portable and battery powered applications requiring high performance and efficient use of board space.
The DG9431 is built on Vishay Siliconix's low voltage BCD-15 process. Minimum ESD protection, per Method 3015.7, is 2000 V. An epitaxial layer prevents latchup. Break-before -make is guaranteed for DG9431.
Low Voltage Operation (+2.7 to +5 V) Low On-Resistance - rDS(on): 20 Fast Switching - tON : 35 ns, tOFF: 20 ns Low Leakage - I COM(on) : 200-pA max Low Charge Injection - QINJ: 1 pC Low Power Consumption TTL/CMOS Compatible ESD Protection > 2000 V (Method 3015.7) Available in TSOP-6 and SOIC-8
