LTC6993IS6-3#TRPBF

Multivibrators Overview

The LTC6993IS6-3#TRPBF is a monostable multivibrator from the TimerBlox family, manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.25V to 5.5V and generates programmable output pulses with widths between 1µs and 33.6 seconds. The pulse duration is set by an external resistor (RSET) connected to the SET pin and an internal clock divider (NDIV) configured via the DIV pin. This specific variant features falling-edge trigger sensitivity and non-retriggerable operation. It is housed in a 6-lead Plastic TSOT-23 package.

Multivibrators Feature Summary

• Configurable as a one-shot pulse generator with falling-edge trigger input
• Programmable pulse width determined by external resistor and internal divider settings
• Capable of generating positive or negative output pulses via polarity control
• Low power consumption with fast recovery time for high-frequency applications

Multivibrators Applications

• Watchdog timer circuits
• Frequency discriminators
• Missing pulse detection systems
• Envelope detectors
• Portable and battery-powered equipment

Multivibrators Procurement Notes

Verify the component matches the exact part number LTC6993IS6-3#TRPBF, ensuring the suffix indicates the correct temperature grade (-40°C to 85°C) and package type (TSOT-23). Confirm authenticity through authorized distributors or direct manufacturer channels. Check for any specific automotive qualification requirements if applicable, though standard industrial grades are typically sufficient for general logic IC applications.

Multivibrators Selection Notes

Select this component when a non-retriggerable monostable circuit with falling-edge triggering is required. Ensure the application voltage stays within the 2.25V to 5.5V range. Consider the NDIV setting and RSET value to achieve the desired pulse width accuracy. Verify that the package footprint matches the PCB design constraints for the 6-lead TSOT-23 form factor.

Multivibrators Part Context

This device belongs to the LTC6993 series of TimerBlox silicon timing devices. The series includes variants with different trigger polarities (rising/falling) and retrigger capabilities (yes/no). The IS6 designation specifically denotes the industrial temperature range and the SOT-23/TSOT-23 package style, distinguishing it from DFN packages or automotive qualified versions.

Multivibrators Replacement Considerations

Direct substitutes include other members of the LTC6993 family such as LTC6993IS6-1#TRPBF (rising-edge, non-retriggerable), LTC6993IS6-2#TRPBF (rising-edge, retriggerable), and LTC6993IS6-4#TRPBF (falling-edge, retriggerable). Ensure the replacement matches the required trigger edge and retrigger functionality.
