It handles both single-supply rails from 10V to 30V and dual supplies from ±4.5V to ±20V, with a maximum on-resistance of 85 Ohm. The 1:1 multiplexer/demultiplexer circuit per channel makes it a straight pass-gate for analog or digital signals. ## Key parametric strengths for analog muxing Crosstalk is rated at -100dB at 1MHz — a strong figure that keeps channel bleed low in precision analog multiplexing, audio routing, or data acquisition front-ends. Charge injection sits at 5pC, which matters for sample-and-hold circuits where injected charge can shift the held voltage. Channel-to-channel on-resistance matching is within 4 Ohm max, helping maintain gain accuracy in multi-channel systems. ## Switching speed and leakage Turn-on time is 250ns max, turn-off 120ns max — fast enough for audio muting, relay replacement, or moderate-speed analog switching. Off-channel leakage current is a maximum 500pA, and channel capacitance (both source and drain off) is 4pF each, so the part loads the signal path lightly in the off state. ## Temperature grade and environment Rated for commercial temperature range 0°C to 70°C. This limits the part to indoor equipment, bench instruments, audio gear, office electronics, and similar environments. Not suited for industrial or automotive applications without a wider-temperature variant. ## Lifecycle and sourcing The DG441CY+T carries an Active lifecycle status and is ROHS3 compliant. It is a current-production part from Maxim Integrated (now part of Analog Devices).","metaTitle":"DG441CY+T Analog Switch IC, SPST-NC x4, 85 Ohm, 16-SOIC","metaDescription":"Maxim Integrated DG441CY+T quad SPST-NC analog switch. 85 Ohm on-resistance, -100dB crosstalk at 1MHz, 5pC charge injection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Crosstalk":"-100dB @ 1MHz","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Switch Circuit":"SPST - NC","lifecycle_stage":"eol_hot","Charge Injection":"5pC","Number of Circuits":"4","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"16-SOIC","On-State Resistance (Max)":"85Ohm","Voltage - Supply, Dual (V±)":"±4.5V ~ 20V","Switch Time (Ton, Toff) (Max)":"250ns, 120ns","Voltage - Supply, Single (V+)":"10V ~ 30V","Current - Leakage (IS(off)) (Max)":"500pA","Multiplexer/Demultiplexer Circuit":"1:1","Channel Capacitance (CS(off), CD(off))":"4pF, 4pF","Channel-to-Channel Matching (ΔRon)":"4Ohm (Max)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.66","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.66000","currency":"USD"},{"qty":10,"price":"$6.01500","currency":"USD"},{"qty":25,"price":"$5.73520","currency":"USD"},{"qty":100,"price":"$4.97990","currency":"USD"},{"qty":250,"price":"$4.75608","currency":"USD"},{"qty":500,"price":"$4.33644","currency":"USD"},{"qty":1000,"price":"$3.77690","currency":"USD"},{"qty":2500,"price":"$3.63701","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/DG441-DG442.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to DG441CY+T?","answer":"Within the same family, the DG441CY+ (non-tape-and-reel variant) shares the same die and 16-SOIC footprint.
