It integrates four independent SPDT switches, each with a 2:1 multiplexer/demultiplexer configuration, giving you eight signal paths that can be individually toggled. The part is designed for precision analog and digital signal switching where low on-resistance, tight channel matching, and minimal crosstalk matter. ## Supply voltage range and what it means for your rails The MAX333AEWP+T accepts a single supply from 10 V to 30 V or dual supplies from ±4.5 V to ±20 V. The 45 Ω maximum on-resistance is consistent across the supply range, and the 2 Ω max channel-to-channel matching keeps gain errors uniform. ## Switching speed, crosstalk, and signal integrity Turn-on time is 175 ns max, turn-off 145 ns max — fast enough for audio multiplexing, relay replacement, and moderate-speed analog muxing. The -78 dB crosstalk at 1 MHz means a signal on one channel won't bleed measurably into an adjacent channel at audio frequencies or low-MHz sampling rates. Off-leakage is 250 pA max, and charge injection is 2 pC typical, both low enough that you won't see offset shifts when switching into a high-impedance load or a sample-and-hold capacitor. ## Package, temperature grade, and lifecycle Housed in a 20-SOIC wide-body package (7.50 mm width), the MAX333AEWP+T is rated for the industrial temperature range of -40°C to 85°C. It is ROHS3 compliant, which covers the current EU exemption requirements.","metaTitle":"MAX333AEWP+T Analog Devices IC Switch SPDT x4, 45Ohm","metaDescription":"MAX333AEWP+T quad SPDT analog switch from Analog Devices. 45Ω on-resistance, 2Ω channel matching, -78dB crosstalk at 1MHz.","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":"-78dB @ 1MHz","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","Switch Circuit":"SPDT","lifecycle_stage":"eol_hot","Charge Injection":"2pC","Number of Circuits":"4","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-SOIC","On-State Resistance (Max)":"45Ohm","Voltage - Supply, Dual (V±)":"±4.5V ~ 20V","Switch Time (Ton, Toff) (Max)":"175ns, 145ns","Voltage - Supply, Single (V+)":"10V ~ 30V","Current - Leakage (IS(off)) (Max)":"250pA","Multiplexer/Demultiplexer Circuit":"2:1","Channel Capacitance (CS(off), CD(off))":"5pF","Channel-to-Channel Matching (ΔRon)":"2Ohm (Max)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.95","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.95000","currency":"USD"},{"qty":10,"price":"$8.99000","currency":"USD"},{"qty":25,"price":"$8.57200","currency":"USD"},{"qty":100,"price":"$7.44290","currency":"USD"},{"qty":250,"price":"$7.10840","currency":"USD"},{"qty":500,"price":"$6.48116","currency":"USD"},{"qty":1000,"price":"$5.64489","currency":"USD"}]},"links":{"datasheetUrl":"https://pdfserv.maximintegrated.com/en/ds/MAX333A.pdf","sourceUrl":null},"ai":{"faq":[{"question":"MAX333AEWP+T vs MAX333A — what is the difference?","answer":"The MAX333AEWP+T is the tape-and-reel variant of the MAX333A family. The base MAX333A die and electrical specs (45 Ω on-resistance, -78 dB crosstalk, 175 ns/145 ns switching times) are identical. The 'T' suffix denotes tape-and-reel packaging for automated assembly; the 'WP' denotes the wide-body 20-SOIC package. If your BOM calls for the tube-packaged version, the MAX333AEWP (without the +T) is the direct equivalent."},{"question":"What is the crosstalk spec for MAX333AEWP+T?","answer":"Crosstalk is -78 dB at 1 MHz, measured between channels. This level of isolation means a signal on one switch path will not couple into an adjacent channel at audio or low-MHz frequencies, making the part suitable for precision multiplexing in data acquisition and audio routing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX333AEWPT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX333AEWPT when reusing this data.
