Each switch handles analog or digital signals with a maximum on-resistance of 175Ohm and channel-to-channel matching held to 1Ohm, so gain errors across channels stay tight. The 250ns turn-on and 150ns turn-off times make it fast enough for audio routing, test equipment signal chains, and data acquisition front-ends where you need to switch between two sources without loading the signal. Charge injection is a low 1.5pC, which matters when you are switching into a high-impedance node like a sample-and-hold or an ADC input — less glitch energy means fewer settling-time headaches. ## Supply rails and where this part lives This switch runs on either a single supply from 9V to 36V or dual supplies from ±4.5V to ±18V. That dual-supply range is the big deal here — it lets you switch bipolar signals without level-shifting or AC coupling. If your design already has ±15V rails for op-amps, this switch drops right onto them. The single-supply mode covers 12V and 24V industrial systems, but watch the signal swing: with a single 12V rail, the switch passes signals from ground up to about 11V, limited by the on-resistance curve. Off-leakage is rated at 20nA max, and channel capacitance is 5pF, so crosstalk stays at -66dB at 1MHz — clean enough for 16-bit audio paths and moderate-frequency analog multiplexing. ## Temperature grade — indoor only The MAX4533CWP+T is rated for the commercial temperature range of 0°C to 70°C. ## Package and mounting for the bench Surface-mount in a 20-SOIC wide-body package (0.295\", 7.50mm width). The wide SOIC gives you more room between pins than the narrow version, which helps when you are hand-soldering a replacement on site with a fine-tip iron. No thermal pad, no exposed paddle — just a straightforward gull-wing package that aligns easily. The T suffix on the order code means it ships in Tape & Reel, but you can also get it as Cut Tape for small quantities. No lab, no bench, let us go — this is a part you can swap in the field with basic tools if you have a steady hand and good lighting. ## Lifecycle and sourcing reality That means you can qualify it into a new BOM without worrying about a last-time-buy window closing next quarter. No LTB math needed, no broker-scramble for obsolete stock.","metaTitle":"MAX4533CWP+T Analog Switch IC, SPDT 4-Ch, 175Ohm, 20-SOIC","metaDescription":"MAX4533CWP+T quad SPDT analog switch from Maxim Integrated. 175Ohm on-resistance, 250ns/150ns switch times, ±4.5V to ±18V dual or 9V to 36V single supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Crosstalk":"-66dB @ 1MHz","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","Switch Circuit":"SPDT","lifecycle_stage":"eol_hot","Charge Injection":"1.5pC","Number of Circuits":"4","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"20-SOIC","On-State Resistance (Max)":"175Ohm","Voltage - Supply, Dual (V±)":"±4.5V ~ 18V","Switch Time (Ton, Toff) (Max)":"250ns, 150ns","Voltage - Supply, Single (V+)":"9V ~ 36V","Current - Leakage (IS(off)) (Max)":"20nA","Multiplexer/Demultiplexer Circuit":"2:1","Channel Capacitance (CS(off), CD(off))":"5pF","Channel-to-Channel Matching (ΔRon)":"1Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.24","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.24000","currency":"USD"},{"qty":10,"price":"$9.25100","currency":"USD"},{"qty":25,"price":"$8.82040","currency":"USD"},{"qty":100,"price":"$7.65860","currency":"USD"},{"qty":250,"price":"$7.31440","currency":"USD"},{"qty":500,"price":"$6.66904","currency":"USD"},{"qty":1000,"price":"$5.80851","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX4533.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX4533CWPT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX4533CWPT when reusing this data.
