DG407CWI+T

Overview

The DG407CWI+T is a CMOS analog multiplexer switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features two independent 8-to-1 multiplexers, providing a total of sixteen channels in a single package. The device operates with a single supply voltage ranging from 5 V to 30 V or dual supplies up to ±20 V. Key electrical specifications include a maximum on-resistance of 175 Ohms, a maximum turn-on time of 600 ns, and a maximum turn-off time of 300 ns. The component supports propagation delays of up to 300 ns and draws a maximum supply current of 500 uA. It is housed in a 16-pin SOIC-Wide package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates two independent 8:1 analog multiplexers for signal routing applications
• Compatible with standard TTL logic levels for control interface simplicity
• Supports flexible power configurations using either single or dual supply voltages

Applications

• Data acquisition systems requiring multi-channel signal selection
• Programmable gain amplifier circuits
• Signal conditioning front-ends in industrial instrumentation

Procurement Notes

Verify the specific suffix +T indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOIC-Wide-16 footprint matches the target PCB layout constraints. Cross-reference the manufacturer part number DG407CWI+T against authorized distributor catalogs to validate authenticity and current production status.

Selection Notes

Select this component when designing circuits that require multiple analog signal paths controlled by digital logic. The 175 Ohm on-resistance limit suits applications where moderate signal attenuation is acceptable. Verify that the 600 ns switching speed meets the system timing requirements. Consider thermal dissipation capabilities if operating near the upper temperature limits of the commercial grade specification.

Part Context

This part belongs to the DG407 series of improved CMOS analog multiplexers. The series typically includes variants such as the DG407CJ+ in PDIP packages and the DG407EWI+ in wider SOIC packages. These devices share common functional architectures but differ in physical packaging and sometimes extended temperature ranges depending on the specific suffix designation.

Replacement Considerations

Direct substitutes include other DG407 series variants like DG407CJ+ or DG407EWI+. Verify pin compatibility and package dimensions before substitution. Check if alternative temperature grades are required for the specific application environment.
