It runs from a 2.25 V to 5.5 V supply and draws 135 µA typical. The TSOT-23-6 package keeps the footprint small, and the -40°C to 125°C operating range suits industrial, automotive, and outdoor equipment where a microcontroller's internal RC timer drifts too much or a crystal is overkill. ## Lifecycle and sourcing The LTC6991HS6#TRMPBF is listed as Active on the manufacturer's lifecycle record, so there is no immediate end-of-life risk for new designs. It is ROHS3 compliant.","metaTitle":"LTC6991HS6#TRMPBF TimerBlox® Silicon Oscillator","metaDescription":"LTC6991HS6#TRMPBF TimerBlox® silicon oscillator, programmable from 29.1 µHz to 977 Hz. 2.25 V to 5.5 V supply, 135 µA supply current, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":"TimerBlox®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Oscillator, Silicon","Series":"TimerBlox®","Package":"Tape & Reel (TR); Cut Tape (CT)","Frequency":"29.1µHz ~ 977Hz","Mounting Type":"Surface Mount","Package / Case":"SOT-23-6 Thin, TSOT-23-6","lifecycle_stage":"eol_hot","Current - Supply":"135 µA","Voltage - Supply":"2.25V ~ 5.5V","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"TSOT-23-6"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.40000","currency":"USD"},{"qty":10,"price":"$5.74500","currency":"USD"},{"qty":25,"price":"$5.43120","currency":"USD"},{"qty":100,"price":"$4.70710","currency":"USD"},{"qty":250,"price":"$4.46572","currency":"USD"},{"qty":500,"price":"$4.00708","currency":"USD"},{"qty":1000,"price":"$3.37946","currency":"USD"},{"qty":2500,"price":"$3.21049","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/LTC6991.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is there an equivalent or replacement for LTC6991HS6#TRMPBF?","answer":"The LTC6995 series (e.g., LTC6995HS6-1#TRMPBF) is a higher-frequency sibling in the same TimerBlox® family and the same TSOT-23-6 package, but it covers a different frequency range — it tops out at 977 Hz as well but starts at a higher minimum. For the ultra-low-frequency range of the LTC6991, there is no direct pin-compatible second source; the LTC6991 is the only TimerBlox® part that goes down to 29.1 µHz."},{"question":"How do I program the LTC6991 oscillator?","answer":"The output frequency is set by connecting a single resistor between the SET pin and ground.
