The pad must be soldered to a PCB thermal land with vias to a ground plane for rated thermal performance. The part is surface-mount only; no through-hole variant exists. Reel and cut-tape options are available for prototyping or production volume. ## Channel matching and capacitance Channel-to-channel on-resistance matching is 100mOhm maximum, which means the four channels present nearly identical resistance to the signal — useful when gain accuracy or attenuation matching matters across channels. Off-channel capacitance is 13pF on the source side and 52pF on the drain side; this capacitance forms a low-pass filter with source impedance, so the designer should account for it in the bandwidth budget.","metaTitle":"MAX4634ETB+T Analog Switch SP4T, 4Ohm, 10-TDFN","metaDescription":"MAX4634ETB+T is a 4:1 analog multiplexer/SP4T switch with 4Ohm max on-resistance, -78dB crosstalk at 1MHz, and 1.8V-5.5V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Crosstalk":"-78dB @ 1MHz","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Switch Circuit":"SP4T","lifecycle_stage":"eol_hot","Charge Injection":"2pC","Number of Circuits":"1","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"10-TDFN (3x3)","On-State Resistance (Max)":"4Ohm","Switch Time (Ton, Toff) (Max)":"18ns, 11ns","Voltage - Supply, Single (V+)":"1.8V ~ 5.5V","Current - Leakage (IS(off)) (Max)":"100pA","Multiplexer/Demultiplexer Circuit":"4:1","Channel Capacitance (CS(off), CD(off))":"13pF, 52pF","Channel-to-Channel Matching (ΔRon)":"100mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.98","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.98000","currency":"USD"},{"qty":10,"price":"$4.47100","currency":"USD"},{"qty":25,"price":"$4.22680","currency":"USD"},{"qty":100,"price":"$3.66330","currency":"USD"},{"qty":250,"price":"$3.47540","currency":"USD"},{"qty":500,"price":"$3.11848","currency":"USD"},{"qty":1000,"price":"$2.63004","currency":"USD"},{"qty":2500,"price":"$2.49854","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/93c5c8d78f9c5db03136428a050db9f5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the on-resistance of MAX4634ETB+T?","answer":"Maximum on-resistance is 4Ohm across the rated supply and temperature range."},{"question":"Is MAX4634ETB+T lead-free?","answer":"Yes, it is ROHS3 compliant, which includes lead-free requirements."},{"question":"What are alternatives to MAX4634ETB+T?","answer":"Pin-compatible alternatives exist within the same Maxim SP4T switch family, such as the MAX4634EUB+ in a 10-uMAX package, but the TDFN package differs.
