It runs on a 2.25V to 5.5V supply and draws 235 µA typical, making it a fit for battery-powered or low-power timing chains where a quartz crystal is overkill or physically too large. ## Supply voltage and frequency range The 2.25V to 5.5V supply range matches 3.3V and 5V rails common in industrial control and sensor interfaces. The 488 Hz to 1 MHz programmable range covers most low-to-mid frequency timing needs — think watchdog clocks, PWM base rates, or simple square-wave generation — without needing an external crystal or ceramic resonator. The TSOT-23-6 package (SOT-23-6 Thin, TSOT-23-6) is a compact surface-mount footprint that fits tight layouts without a dedicated oscillator footprint. ## Active lifecycle and sourcing posture It is ROHS3 compliant. Sourced per RFQ against your BOM quantity; current pricing and lead time confirmed at quote time.","metaTitle":"LTC6990IS6#TRMPBF Analog Devices TimerBlox® Silicon","metaDescription":"LTC6990IS6#TRMPBF silicon oscillator, 488 Hz to 1 MHz, 2.25V to 5.5V supply, 235 µA, -40°C to 85°C, TSOT-23-6.
