Package and mounting
The LTC6991MPS6#TRMPBF is a silicon oscillator from the TimerBlox® family — no crystal, no RC network, just a resistor to set the period. The frequency range spans from 29.1 µHz up to 977 Hz. Supply current stays at 135 µA regardless of output frequency. The TSOT-23-6 package keeps the footprint small.
Military temperature grade — the MPS6 suffix
The MPS6 suffix indicates the -55°C to 125°C operating range. The HS6 variant (LTC6991HS6#TRMPBF) covers -40°C to 125°C — same die, same frequency range, same package, but the M grade extends the cold side down to -55°C. The supply voltage covers 2.25 V to 5.5 V.
