DG428DJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG428DJ-E3 is a single-supply or dual-supply analog multiplexer manufactured by Vishay Siliconix. It features eight single-ended inputs and one common output, housed in an 18-pin Plastic DIP package. The device incorporates on-chip TTL-compatible address latches to simplify microprocessor interfacing. Key electrical parameters include a maximum on-resistance of 100 Ω at room temperature (rising to 125 Ω across the full -40 °C to +85 °C range), a transition time of up to 300 ns, and charge injection of 1 pC. It operates with supply voltages ranging from 0 V to 12 V for single supply or ±15 V for dual supply configurations.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your project timeline. Ensure proper handling procedures are followed due to ESD sensitivity inherent to CMOS technology.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when designing systems requiring latchable analog switching to reduce board space and interface hardware. Consider the 100 Ω on-resistance and 300 ns switching speed against system requirements. Verify that the 18-pin DIP footprint matches your PCB layout constraints and that the operating temperature range meets environmental specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG4xx series of analog multiplexers produced by Vishay Siliconix. It shares functional similarities with the DG429 but differs in channel configuration, offering eight single-ended inputs instead of four differential pairs. The 'E3' suffix indicates compliance with current environmental directives.
