It routes one of four differential inputs to a common output per channel, with two independent switch circuits on-chip. The part is specified for single-supply operation from 5V to 30V or dual supplies from ±5V to 20V. ## Key specs for signal integrity and routing On-resistance is 100 Ohm maximum, with channel-to-channel matching of 1.5 Ohm, which keeps insertion loss and attenuation predictable across channels. Switching time is 150 ns for both turn-on and turn-off, fast enough for moderate-speed analog multiplexing. Charge injection is 2 pC, a consideration for sample-and-hold or precision integrator circuits where glitch energy matters. Off-leakage current is 500 pA maximum, and channel capacitance is 3 pF (source off) and 14 pF (drain off), which together define the off-isolation and signal feedthrough at higher frequencies. Crosstalk between channels is -92 dB at 100 kHz, a strong figure for audio-frequency multiplexing or multi-channel data acquisition where channel bleed must be minimized. ## Temperature grade and deployment environment Rated for the commercial temperature range of 0°C to 70°C, the DG409CY+ is intended for indoor, controlled-environment equipment such as benchtop instruments, audio gear, telecom line cards, and lab automation. It is not specified for industrial or automotive under-hood environments where extended temperature operation is required. ## Lifecycle and sourcing The DG409CY+ is listed as Active in production with ROHS3 compliance.","metaTitle":"DG409CY+ Dual SP4T Analog Multiplexer, 100 Ohm On-Resistance","metaDescription":"DG409CY+ dual 4:1 multiplexer from Maxim Integrated. 100 Ohm max on-resistance, -92dB crosstalk at 100kHz, single/dual supply, 16-SOIC.
