DG419BDY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The Vishay Siliconix DG419BDY-E3 is a precision monolithic quad SPDT CMOS analog switch housed in an 8-pin narrow SOIC package. It operates within a temperature range of -40 °C to +85 °C and supports dual supply voltages up to ±20 V or single supplies up to 44 V. The device features a maximum on-resistance of 25 Ω at room temperature, rising to 45 Ω across the full operating range. Key dynamic parameters include a turn-on time of 89 ns and a turn-off time of 80 ns under ±15 V conditions. It provides break-before-make switching action and includes an epitaxial layer to prevent latchup.
