It routes one of two inputs to a common output, or splits a common signal to one of two outputs. Key specs include a maximum on-resistance of 60 Ohm, channel-to-channel matching of 800 mOhm, and crosstalk of -90 dB at 1 MHz. The switch operates from a single supply of 2.7 V to 12 V. It is housed in an 8-SOIC surface-mount package and rated for the industrial temperature range of -40 °C to 85 °C. Typical applications include audio signal routing, analog multiplexing, relay replacement, and data acquisition front-ends in factory automation, telecom infrastructure, and instrumentation. ## On-resistance and signal integrity The 60 Ohm max on-resistance is moderate for a general-purpose analog switch. It introduces insertion loss that must be budgeted in the signal path, particularly for low-impedance loads. The 800 mOhm channel-to-channel matching ensures consistent attenuation when switching between two sources, which matters for gain-matched or differential signals. The -90 dB crosstalk at 1 MHz is strong — this switch will not bleed a 1 MHz signal from one channel into the other, making it suitable for audio or low-frequency precision analog multiplexing where isolation is critical. ## Switching speed and charge injection Turn-on time is 100 ns max, turn-off 75 ns max. That is fast enough for audio muting, relay replacement, and low-frequency analog muxing, but not for video or high-speed data switching. Charge injection is 1 pC — low enough that the switch will not glitch a sample-and-hold or precision ADC input beyond a few millivolts, depending on the hold capacitance. Off-leakage is 100 pA max, which is negligible for most signal-chain designs. ## Supply voltage and temperature range Single-supply operation from 2.7 V to 12 V covers 12 V industrial analog supplies. The industrial temperature grade of -40 °C to 85 °C suits outdoor telecom cabinets, factory-floor controllers, and engine-bay-adjacent electronics. The 8-SOIC package is a standard footprint, easily hand-solderable or machine-placed.","metaTitle":"MAX4544ESA+T Analog Devices SPDT Switch, 60 Ohm, 8-SOIC","metaDescription":"MAX4544ESA+T Analog Devices SPDT analog switch, 60 Ohm on-resistance, -90 dB crosstalk at 1 MHz. 2.7 V to 12 V supply, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Crosstalk":"-90dB @ 1MHz","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Switch Circuit":"SPDT","lifecycle_stage":"eol_hot","Charge Injection":"1pC","Number of Circuits":"1","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","On-State Resistance (Max)":"60Ohm","Switch Time (Ton, Toff) (Max)":"100ns, 75ns","Voltage - Supply, Single (V+)":"2.7V ~ 12V","Current - Leakage (IS(off)) (Max)":"100pA","Multiplexer/Demultiplexer Circuit":"2:1","Channel Capacitance (CS(off), CD(off))":"8pF, 8pF","Channel-to-Channel Matching (ΔRon)":"800mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.56","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.56000","currency":"USD"},{"qty":10,"price":"$2.30200","currency":"USD"},{"qty":25,"price":"$2.17160","currency":"USD"},{"qty":100,"price":"$1.85010","currency":"USD"},{"qty":250,"price":"$1.73720","currency":"USD"},{"qty":500,"price":"$1.52004","currency":"USD"},{"qty":1000,"price":"$1.25947","currency":"USD"},{"qty":2500,"price":"$1.17261","currency":"USD"},{"qty":5000,"price":"$1.12918","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX4541-MAX4544.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the on-resistance of MAX4544ESA+T?","answer":"The maximum on-resistance is 60 Ohm.
