LTC6995CDCB-2#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6995CDCB-2#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 device operates on a single supply voltage between 2.25V and 5.5V with a typical supply current ranging from 55µA to 80µA depending on the clock period. Frequency is set by an external resistor RSET connected to the SET pin, while the output divider ratio NDIV is selected via the DIV pin. This specific part number denotes the -2 version with active-low reset functionality, housed in a 6-lead DFN package.

Programmable Timers And Oscillators Feature Summary

• Programmable frequency range from 29.1µHz to 977Hz using a single external resistor
• Active-low reset input characteristic of the LTC6995-2 variant
• CMOS output driver capable of sourcing and sinking 20mA
• Specified operating temperature range of 0°C to 70°C

Programmable Timers And Oscillators Applications

• Power-on reset timers
• Watchdog timers
• Periodic wake-up calls
• Long time one-shot circuits

Programmable Timers And Oscillators Procurement Notes

Verify the ordering suffix #TRMPBF indicates mini tape and reel packaging containing 500 units. Confirm the CDCB designation corresponds to the commercial grade temperature range of 0°C to 70°C within the 6-lead DFN package. Ensure the -2 suffix matches system requirements for active-low reset logic polarity.

Programmable Timers And Oscillators Selection Notes

Select this component when low-frequency oscillation up to approximately 9.5 hours is required. The LTC6995-2 variant must be chosen if the control system utilizes an active-low signal for the reset function. Verify that the application environment remains within the 0°C to 70°C specified temperature range for guaranteed performance.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6995 series of TimerBlox silicon oscillators. The CDCB suffix identifies the commercial temperature grade and plastic DFN package. The -2 suffix distinguishes it from the -1 version by providing an active-low reset input instead of active-high. The TRMPBF suffix specifies the mini tape and reel packaging format.

Programmable Timers And Oscillators Replacement Considerations

LTC6995CDCB-1#TRMPBF differs only in reset polarity (active-high vs active-low). LTC6995IDCB-2#TRMPBF offers the same electrical characteristics but supports a wider industrial temperature range of –40°C to 85°C.
