DG442DY-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442DY-T is a monolithic CMOS analog switch IC manufactured by Renesas Electronics Corporation. It integrates four independent single-pole single-throw (SPST) normally open switches within a 16-pin SOIC-Narrow package. The device supports single supply voltages ranging from 5 V to 34 V or dual supplies from ±5 V to ±22 V. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum operating speed of 250 ns for turn-on and 210 ns for turn-off, and a maximum power supply current of 100 uA. It operates reliably across an extended temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DY-T' against official Renesas documentation to confirm tape-and-reel packaging and industrial temperature grade specifications. Ensure compatibility with moisture sensitivity level requirements during assembly. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring four isolated analog signal paths with moderate on-resistance. Consider the 85 Ohm on-resistance limit for voltage drop calculations in sensitive signal chains. Verify that the required signal swing remains within the specified single or dual supply voltage limits to prevent latch-up or damage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG44x series of monolithic CMOS analog switches produced by Renesas Electronics. It serves as a functional alternative to legacy Intersil devices, maintaining pin compatibility while offering improved performance metrics such as reduced charge injection and faster switching speeds compared to older generation switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG442DYZ is a verified equivalent variant featuring identical electrical characteristics but packaged in tubes rather than tape-and-reel format. Designers must verify footprint compatibility if transitioning between tube and reel packaging types.
