LTC6993IS6-3#TRMPBF

Multivibrators Overview

The LTC6993IS6-3#TRMPBF is a monostable multivibrator from the TimerBlox family, packaged in a 6-lead Plastic TSOT-23. It generates output pulses with widths ranging from 1µs to 33.55 seconds. The pulse duration is programmed via an external resistor (RSET) connected to the SET pin and a divider code (NDIV) set by the DIV pin voltage. This specific variant triggers on a falling edge and is non-retriggerable. It operates on a single supply voltage between 2.25V and 5.5V.

Multivibrators Feature Summary

• Configurable as a one-shot pulse generator with programmable width
• Falling-edge trigger input for signal initiation
• Non-retriggerable operation mode
• Single-supply operation with low current consumption

Multivibrators Applications

• Watchdog timer circuits
• Frequency discriminators
• Missing pulse detection systems
• Envelope detectors
• High vibration or acceleration environments

Multivibrators Procurement Notes

Verify the exact part number against official Analog Devices documentation to confirm the IS6 package and -3 suffix specifications. Ensure compatibility with the required operating temperature range of –40°C to 85°C. Confirm that the non-retriggerable falling-edge trigger configuration matches the system design requirements before procurement.

Multivibrators Selection Notes

Select this component when a falling-edge triggered, non-retriggerable monostable pulse is required. The IS6 package offers a compact SMD solution suitable for space-constrained designs. Consider the NDIV settings and RSET resistor tolerance to achieve the necessary pulse width accuracy and stability across the specified temperature range.

Multivibrators Part Context

This device belongs to the LTC6993 series of TimerBlox silicon timing devices. It shares functional similarities with other variants in the family, such as the LTC6993-1, -2, and -4, which differ primarily in trigger polarity and retrigger capability. The IS6 designation indicates the industrial temperature grade and TSOT-23 packaging.

Multivibrators Replacement Considerations

LTC6993IS6-1#TRMPBF: Rising-edge trigger, non-retriggerable. LTC6993IS6-2#TRMPBF: Rising-edge trigger, retriggerable. LTC6993IS6-4#TRMPBF: Falling-edge trigger, retriggerable.
