LTC6993CDCB-3#TRMPBF

Multivibrators Overview

The LTC6993CDCB-3#TRMPBF is a monostable multivibrator from the TimerBlox family, housed in a 6-lead DFN package. It generates output pulses with widths ranging from 1µs to 33.55 seconds. The pulse duration is set by an internal master oscillator and a programmable divider (NDIV). This specific variant triggers on a falling edge and lacks retrigger capability. It operates on a single supply voltage between 2.25V and 5.5V.

Multivibrators Feature Summary

• Configurable for negative output pulses via DIV pin settings
• Triggered exclusively by falling-edge transitions on the input
• Non-retriggerable architecture ignores subsequent triggers during active state
• CMOS output driver capable of sourcing and sinking current

Multivibrators Applications

• Watchdog timer circuits
• Missing pulse detection systems
• Envelope detectors
• Frequency discriminators

Multivibrators Procurement Notes

Verify the component matches the specified temperature range of 0°C to 70°C. Confirm the package type is the 6-lead plastic DFN. Ensure the ordering suffix corresponds to the tape and reel mini packaging format. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm authenticity.

Multivibrators Selection Notes

Select this variant when a non-retriggerable response to falling-edge signals is required. It is suitable for applications where the output pulse must complete without interruption from additional trigger events. Consider the operating temperature limits and the specific divider settings needed for the desired pulse width range.

Multivibrators Part Context

This device belongs to the LTC6993 series of silicon timing devices. It shares functional similarities with other variants that offer rising-edge triggering or retriggerable modes. The CDCB-3 designation specifically identifies the commercial temperature grade, DFN package, and falling-edge non-retriggerable configuration within the broader product line.

Multivibrators Replacement Considerations

LTC6993IDCB-3#TRMPBF offers the same functionality but with an extended industrial temperature range.
