Each of its two independent switches routes a single analog or digital signal with a 1:1 multiplexer/demultiplexer topology, meaning the channel is either open (off) or closed (on) with no internal mux routing. The normally-closed configuration means the switch conducts when the control input is at a logic low — a useful fail-safe for signals that must remain connected through a power-loss or reset event. The 75 ohm maximum on-resistance sets the insertion loss for the signal path — for a 10 kΩ load the attenuation is negligible, but driving a 600 Ω audio line the voltage drop becomes measurable. The 3 ohm channel-to-channel matching means the two switches track within 4% of each other, which matters for differential signals or gain-matched paths where a resistance mismatch would unbalance the circuit. Charge injection of 15 pC is the amount of charge dumped onto the signal node when the switch turns off. In a sample-and-hold front end this translates to a voltage error of 15 pC / hold capacitance — a 100 pF hold cap sees a 150 mV glitch, so the designer must either increase the hold cap or post-filter the output. The 150 ns turn-on and 125 ns turn-off times are fast enough for audio-frequency multiplexing and moderate-speed data acquisition, but not for video-rate switching. Off-leakage of 100 nA maximum is the current that bleeds through the open switch. At 25°C the typical leakage is lower, but at 125°C it can approach the maximum. For a 10 MΩ input impedance the 100 nA leakage produces a 1 V offset error — something to budget for in high-impedance sensor interfaces. ## Supply voltage and temperature range The dual-supply capability lets the switch handle bipolar signals up to the rail limits, which is typical for op-amp-based analog front ends. ## Package and mounting reality The IH5141MTW comes in a TO-100-10 metal can package, a through-hole circular header with 10 leads arranged in a 9.4 mm diameter circle. Through-hole mounting means hand-assembly or wave-solder only — no reflow profile. The metal can provides a hermetic seal and good thermal conductivity to the board, but the package height (about 5.8 mm) limits use in low-profile enclosures. ## Lifecycle and compliance However, it is RoHS non-compliant — the leads and internal construction contain lead and possibly other restricted substances. For designs that must meet RoHS 2 or 3 directives, this part cannot be used unless an exemption applies (e.g., military or aerospace equipment). ## Sourcing this part Because the IH5141MTW is an active, RoHS-non-compliant part in a through-hole hermetic package, its primary channel is through authorized semiconductor distributors and specialty high-reliability suppliers. The military temperature grade and metal can package mean the part is also stocked by surplus and obsolescence-management houses serving the defence and aerospace aftermarket.","metaTitle":"IH5141MTW Low Power Fast Analog Switch, SPST-NC, 75Ohm","metaDescription":"IH5141MTW dual SPST-NC analog switch, 75 ohm max on-resistance, 15pC charge injection, ±4.5V to 18V dual supply, -55°C to 125°C, TO-100-10 metal can.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Bulk","Mounting Type":"Through Hole","Package / Case":"TO-100-10 Metal Can","Switch Circuit":"SPST - NC","lifecycle_stage":"eol_hot","Charge Injection":"15pC","Number of Circuits":"2","Operating Temperature":"-55°C ~ 125°C (TA)","Supplier Device Package":"TO-100-10","On-State Resistance (Max)":"75Ohm","Voltage - Supply, Dual (V±)":"±4.5V ~ 18V","Switch Time (Ton, Toff) (Max)":"150ns, 125ns","Voltage - Supply, Single (V+)":"4.5V ~ 18V","Current - Leakage (IS(off)) (Max)":"100nA","Multiplexer/Demultiplexer Circuit":"1:1","Channel-to-Channel Matching (ΔRon)":"3Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.08","stockQuantity":0,"priceTiers":[{"qty":25,"price":"$12.08000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/db4334451cea516d5c218b07bfe2567f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the on-resistance of IH5141MTW?","answer":"The maximum on-resistance is 75 ohms per channel, with channel-to-channel matching within 3 ohms.
