LTC6995IS6-1#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6995IS6-1#TRMPBF is a silicon oscillator from the TimerBlox family, designed for long duration timing events. It features a programmable period range of 1.024ms to 9.54 hours (29.1µHz to 977Hz). The output clock period is determined by an internal master oscillator and a programmable frequency divider (NDIV) with eight settings from 1 to 221. A single resistor, RSET, programs the internal master oscillator frequency. The device generates a 50% duty cycle square wave output and includes a reset function to stop the oscillator and clear dividers. It operates on a single supply voltage of 2.25V to 5.5V.

Programmable Timers And Oscillators Feature Summary

• Programmable period range from 1.024ms to 9.54 hours using a single external resistor

• Heartbeat Timers

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates Mini Tape and Reel packaging containing 500 units. Confirm the IS6 designation corresponds to the SOT-23 package and the industrial temperature range of –40°C to 85°C. Ensure the -1 variant matches the required active-high reset logic for the design.

Programmable Timers And Oscillators Selection Notes

Select this part when a long timer or low-frequency oscillator is needed with minimal component count. Use the -1 version for active-high reset requirements. Calculate RSET based on the desired period and selected NDIV value. Ensure the operating temperature range meets the application's environmental specifications.

Programmable Timers And Oscillators Part Context

This component belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. The LTC6995 series offers multiple versions differentiated by reset polarity (-1 vs -2), temperature grade (C, I, H, MP), and package type (S6 TSOT-23 or DCB DFN). The IS6-1 variant specifically targets industrial applications requiring an active-high reset in a compact surface-mount package.

Programmable Timers And Oscillators Replacement Considerations

LTC6995HS6-1#TRMPBF: Higher temperature grade (-40°C to 125°C). LTC6995CS6-1#TRMPBF: Commercial temperature grade (0°C to 70°C). LTC6995IDCB-1#TRMPBF: Same electrical specs but in DFN package.
