LTC6993IS6-2#TRPBF

Multivibrators Overview

The LTC6993IS6-2#TRPBF is a monostable multivibrator from the TimerBlox family, packaged in a 6-lead Plastic TSOT-23. It operates on a single supply voltage ranging from 2.25V to 5.5V with an operating temperature range of –40°C to 85°C. The device generates output pulses with widths programmable from 1µs to 33.55 seconds using a single external resistor and internal divider settings. It features rising-edge triggering with retrigger capability, allowing pulse extension by subsequent trigger signals. The CMOS output driver sources and sinks up to 20mA.

Multivibrators Feature Summary

• Retriggerable monostable operation initiated by rising-edge triggers
• Programmable pulse width via single resistor and internal clock divider
• Configurable output polarity through DIV pin voltage setting
• Low power consumption suitable for battery-powered applications

Multivibrators Applications

• Watchdog timers
• Frequency discriminators
• Missing pulse detection circuits
• Envelope detectors

Multivibrators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the IS6 designation corresponds to the industrial temperature grade and TSOT-23 package. Ensure compatibility with existing board layouts requiring this specific footprint and thermal characteristics. Check for automotive qualified variants if higher reliability standards are required for the application environment.

Multivibrators Selection Notes

Select this variant for designs requiring rising-edge triggered retriggerable pulse generation within the industrial temperature range. Compare against non-retriggerable versions (LTC6993-1/3) or falling-edge sensitive models (LTC6993-3/4) based on input signal characteristics. Consider the DFN package option if space constraints differ from the TSOT-23 form factor requirements.

Multivibrators Part Context

This component belongs to the Analog Devices TimerBlox family of silicon timing devices. It shares architectural similarities with other LTC699x series parts but differs in trigger polarity and retrigger functionality. The IS6 suffix specifically denotes the industrial temperature grade and surface-mount TSOT-23 packaging configuration.

Multivibrators Replacement Considerations

Direct functional substitutes include other LTC6993 variants such as LTC6993IS6-1#TRPBF for non-retriggerable rising-edge applications, or LTC6993IS6-3#TRPBF for falling-edge non-retriggerable use cases. Cross-series replacements may require circuit redesign due to differing trigger logic.
