LTC6993IDCB-3#TRPBF

Multivibrators Overview

The LTC6993IDCB-3#TRPBF is a monostable multivibrator from Analog Devices' TimerBlox family, housed in a 6-lead 2mm × 3mm Plastic DFN package. 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 programmable output pulses between 1µs and 33.6 seconds, configured via a single SET resistor and a DIV pin setting. It features falling-edge trigger sensitivity without retrigger capability, producing negative output pulses by default.

Multivibrators Feature Summary

• Monostable pulse generation with programmable width from 1µs to 33.6 seconds
• Falling-edge trigger input with non-retriggerable operation
• Configurable output polarity and divider ratio via DIV pin voltage
• Low power consumption with fast recovery time for high-frequency applications

Multivibrators Applications

• Watchdog timer circuits
• Frequency discriminators
• Missing pulse detection systems
• Envelope detection in modulated signal processing

Multivibrators Procurement Notes

Verify the specific suffix IDCB-3 corresponds to the Industrial temperature grade (-40°C to 85°C), DFN package, and Falling-Edge/Non-Retriggerable configuration. Confirm the #TRPBF indicates Tape and Reel packaging. Ensure the source document explicitly lists this part number in the Order Information table to validate availability and exact electrical specifications before procurement.

Multivibrators Selection Notes

Select this variant when falling-edge triggering is required and retriggering is undesirable. The IDCB-3 designation ensures compatibility with industrial temperature ranges and compact DFN footprints. Verify that the DIV pin voltage settings align with the desired NDIV and output polarity requirements. Consider the 70µA supply current at short pulse widths for battery-powered designs.

Multivibrators Part Context

This component belongs to the LTC6993-1 through LTC6993-4 series, differentiated by trigger edge polarity and retrigger functionality. The '3' suffix specifically denotes the Falling-Edge trigger with Non-Retriggerable behavior. It shares the same core TimerBlox architecture as other variants but offers distinct interface logic for specific timing control needs.

Multivibrators Replacement Considerations

LTC6993HDCB-3#TRPBF for extended temperature range (-40°C to 125°C). LTC6993CDCB-3#TRPBF for commercial temperature range (0°C to 70°C). Other variants like LTC6993IDCB-1 or -2 differ in trigger edge or retrigger capability.
