LTC6993CDCB-4#TRMPBF

Multivibrators Overview

The LTC6993CDCB-4#TRMPBF is a monostable multivibrator from the TimerBlox family, housed in a 6-lead DFN package with an operating temperature range of 0°C to 70°C. It generates programmable output pulses ranging from 1µs to 33.6 seconds using a single external resistor and internal divider settings. The device features falling-edge trigger sensitivity and retrigger capability, allowing pulse extension. It operates on a single supply voltage between 2.25V and 5.5V, drawing as low as 70µA at specific configurations.

Multivibrators Feature Summary

• Generates precise monostable output pulses with widths programmable from 1 microsecond to 33.6 seconds via a single resistor and internal clock divider.
• Supports dynamic pulse width adjustment through a separate control voltage input for flexible timing applications.
• Configurable for positive or negative output pulse polarity and offers both rising-edge and falling-edge trigger options across the family.
• Includes retriggerable functionality that allows the output pulse duration to be extended by subsequent trigger signals while active.

Multivibrators Applications

• Watchdog timer circuits requiring reliable reset signal generation
• Frequency discriminators for signal analysis
• Missing pulse detection systems
• Envelope detectors in communication receivers

Multivibrators Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel mini packaging when sourcing. Confirm the CDCB variant corresponds to the commercial temperature grade (0°C to 70°C) rather than industrial or high-temperature grades. Ensure the ordering code matches the required trigger polarity and retrigger capability defined by the -4 designation. Cross-reference the manufacturer part number against official Analog Devices documentation to avoid counterfeit components.

Multivibrators Selection Notes

Select this component when a falling-edge triggered, retriggerable monostable pulse generator is required within commercial temperature limits. The -4 suffix specifically denotes falling-edge sensitivity with retrigger capability. Consider the DFN package for space-constrained designs. Evaluate the NDIV setting and RSET value to ensure the desired pulse width falls within the specified accuracy ranges for the application.

Multivibrators Part Context

This part belongs to the LTC6993 series of TimerBlox silicon timing devices, which are versatile monostable multivibrators. The series includes variants with different trigger polarities and retrigger capabilities, packaged in DFN and SOT-23 formats. The LTC6993-4 specifically provides falling-edge triggering with retrigger support, distinguishing it from non-retriggerable or rising-edge versions in the same family.

Multivibrators FAQ

What is the trigger polarity for the LTC6993-4?

The LTC6993-4 is sensitive to falling-edge triggers on the TRIG pin.

Can the output pulse width be extended after the trigger has occurred?

Yes, the LTC6993-4 is retriggerable, meaning additional trigger signals can extend the output pulse width indefinitely while the device is active.
