That bottom end is where this part earns its keep: watchdog timers, power-up sequencing delays, periodic wake-up intervals that a resistor-capacitor network cannot hold with any repeatability. Supply current is 135 µA typical, which keeps the timing block alive on a coin cell or a lightly loaded rail without draining the system budget. The part is listed as a silicon oscillator — no external crystal, no load-capacitance matching, no drive-level calculation. Frequency is set by one external resistor; the internal PLL and divider chain do the rest. ## Supply range and temperature grade — commercial-only envelope Operating supply spans 2.25 V to 5.5 V, covering logic rails without a separate regulator. ## Active production — no end-of-life watch needed Product status is Active, meaning Analog Devices continues to manufacture and support this order code. ROHS3 compliant. Available in Tape & Reel (TR) and Cut Tape (CT) options.","metaTitle":"LTC6991CS6#TRMPBF Analog Devices TimerBlox® Silicon","metaDescription":"LTC6991CS6#TRMPBF Analog Devices TimerBlox® silicon oscillator, 29.1µHz to 977Hz, 135 µA supply, TSOT-23-6.
