DG412LDY

Analog Switches, Multiplexers, Demultiplexers Overview

The Vishay Siliconix DG412LDY is a precision monolithic quad single-pole single-throw (SPST) low-voltage CMOS analog switch. It operates on single supplies from 2.7 V to 12 V or dual supplies of ±3 V to ±6 V. The device features a maximum drain-source on-resistance of 17 Ω, turn-on time of 19 ns, and turn-off time of 12 ns. It supports TTL and CMOS logic inputs with low leakage current of 0.25 nA and provides 2000 V ESD protection. The component is housed in a 16-pin narrow SOIC package.
