DG211CYZT

Analog Switches, Multiplexers, Demultiplexers Overview

The DG211CYZT is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Renesas Electronics Corporation. It features four independent switches with TTL and CMOS compatible digital inputs, designed as a drop-in replacement for the DG211 series. The device utilizes a high-voltage silicon-gate process to achieve an ON-resistance of 35Ω maximum and fast switching times of 175ns (tON) and 145ns (tOFF). It supports single supply voltages from +5V to +44V or split supplies from ±5V to ±20V, allowing control of 40V peak-to-peak signals. Key electrical characteristics include low power consumption under 35µW, charge injection of 5pC, and leakage current of 0.1nA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific package markings against official datasheets. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package damage prior to soldering.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when requiring quad SPST switching with low charge injection and high voltage tolerance. Compare ON-resistance and switching speed specifications against system timing requirements. Verify that the available supply voltage range aligns with the application's power architecture and signal swing limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG211/DG411 family of analog switches. It shares functional similarities with the DG411 but differs in selection logic polarity. The DG211 series is characterized by positive logic where a logic high turns the switch on, distinguishing it from the negative logic variants in the same product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411 series serves as a direct functional upgrade with improved performance metrics. Designers should verify logic polarity differences between DG211 and DG411 variants to ensure correct control signal interfacing without external logic modifications.
