DG429DJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG429DJ-E3 is a Vishay Siliconix analog multiplexer featuring four differential channels in an 18-pin Plastic DIP package. It operates with dual supplies of ±15 V or a single supply up to 12 V, supporting analog signals across the full rail range. The device includes on-chip TTL-compatible address latches and break-before-make switching to prevent crosstalk. Key electrical parameters include a maximum on-resistance of 100 Ω at room temperature, a transition time of 250 ns, and a charge injection of 1 pC. It functions within a temperature range of -40 °C to +85 °C.
