Overview
The DG9431DY-T1 is a low-voltage single SPDT analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of 2.7 V to 5 V, with an absolute maximum rating up to 12 V. The device features a maximum on-resistance of 30 Ω at room temperature and 50 Ω across the full operating temperature range (-40 °C to +85 °C). Switching times are specified as a maximum turn-on time of 150 ns and a turn-off time of 100 ns at 5 V. Leakage currents are limited to 100 pA at room temperature and 10 nA at full temperature range. The component is housed in an SOIC-8 package.
