Each switch presents a maximum on-resistance of 4 Ohms, with channel-to-channel matching held to 200 mOhms — tight enough that gain errors across channels stay within a fraction of a percent in precision analog paths. The 1:1 mux/demux topology means each switch is a single-pole pass gate, not a multiplexer; you route one signal per channel, on or off. ## Supply rails and signal headroom This part runs from a single supply between 4.5 V and 36 V, or from dual supplies spanning ±4.5 V to ±20 V. The wide range covers both single-rail battery systems and split-rail industrial analog front-ends. Switching times are 120 ns on, 130 ns off — fast enough for 1 MHz audio crosspoint or low-speed data acquisition muxing. Crosstalk between channels measures -60 dB at 1 MHz, which keeps channel bleed below the noise floor in 12-bit systems. ## Charge injection and leakage — what to watch Charge injection is specified at 225 pC. In a sample-and-hold or integrator front-end, that level of injected charge can cause a voltage step across the hold capacitor; budget for it in the acquisition chain. Off-leakage is a maximum 500 pA at 25 °C, so the switch holds its state well in high-impedance circuits. Each channel presents 34 pF of capacitance to ground when off — factor that into the RC settling time if you are switching into a high-source-impedance node. ## Temperature grade and environment Rated for commercial temperature range, 0 °C to 70 °C. That covers benchtop instrumentation, office equipment, and indoor industrial control panels. Not specified for automotive or extended industrial environments; if your application sees -40 °C or +85 °C ambient, look at the MAX4604's industrial-grade variant or a different switch family. ## Lifecycle and sourcing The MAX4604CSE+ carries an Active product status per the manufacturer, and it is ROHS3 compliant. No direct pin-compatible second source is listed in the available documentation, so dual-sourcing would require a board-level qualification of a functionally equivalent switch from another vendor.","metaTitle":"MAX4604CSE+ 4-Channel SPST-NC Analog Switch","metaDescription":"Maxim MAX4604CSE+ 4-channel SPST-NC analog switch in 16-SOIC. 4 Ohm max on-resistance, 200 mOhm channel matching, 120 ns switching.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Crosstalk":"-60dB @ 1MHz","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Switch Circuit":"SPST - NC","lifecycle_stage":"eol_hot","Charge Injection":"225pC","Number of Circuits":"4","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"16-SOIC","On-State Resistance (Max)":"4Ohm","Voltage - Supply, Dual (V±)":"±4.5V ~ 20V","Switch Time (Ton, Toff) (Max)":"120ns, 130ns","Voltage - Supply, Single (V+)":"4.5V ~ 36V","Current - Leakage (IS(off)) (Max)":"500pA","Multiplexer/Demultiplexer Circuit":"1:1","Channel Capacitance (CS(off), CD(off))":"34pF, 34pF","Channel-to-Channel Matching (ΔRon)":"200mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.92000","currency":"USD"},{"qty":10,"price":"$8.05600","currency":"USD"},{"qty":25,"price":"$7.68160","currency":"USD"},{"qty":100,"price":"$6.66980","currency":"USD"},{"qty":250,"price":"$6.37008","currency":"USD"},{"qty":500,"price":"$5.80800","currency":"USD"},{"qty":1000,"price":"$5.05858","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX4604-MAX4606.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the on-resistance of MAX4604CSE+?","answer":"Maximum on-resistance is 4 Ohms, with channel-to-channel matching of 200 mOhms."},{"question":"What is the closest pin-compatible alternative to MAX4604CSE+?","answer":"No pin-compatible second source is listed in the available documentation.
