29.1 µHz to 977 Hz — silicon oscillator in TSOT-23-6
The LTC6995HS6-2#TRMPBF is a silicon oscillator from the TimerBlox® family, programmable across 29.1 µHz to 977 Hz. This sub-1 kHz range is unusual for a silicon oscillator — it targets very-long-period timing, watchdog timeouts, and low-frequency pulse generation where a quartz crystal would be oversized or unavailable. Supply current is 135 µA typical, and the operating supply range spans 2.25 V to 5.5 V, so it runs directly off a 3.3 V or 5 V rail without a series regulator. The wide voltage headroom also helps when the rail droops under load.
The TSOT-23-6 package keeps the board footprint small — six pins, no thermal pad to worry about — but the narrow pitch means the reflow profile must match the lead-free solder paste specified for ROHS3 compliance.
Active production — current lifecycle status
Analog Devices lists the LTC6995HS6-2#TRMPBF as Active. The part is ROHS3 compliant, which covers the current EU exemption list — no red-flag substances in the bill of materials. Sourced per RFQ against your BOM quantity. No stock-holding claim — we quote to order.
Sibling comparison — LTC6995HS6-1#TRMPBF vs LTC6995HDCB-1#TRMPBF
The TimerBlox® family includes several LTC6995 variants. The LTC6995HS6-1#TRMPBF shares the same TSOT-23-6 package and 977 Hz maximum frequency. The LTC6995HDCB-1#TRMPBF and LTC6995HDCB-2#TRMPBF use the DFN package instead. All are silicon oscillators with the same supply voltage and temperature range — the key difference is the package footprint and the programming resistor value that sets the frequency.
