LTC6993HDCB-1#TRPBF

Multivibrators Overview

The LTC6993HDCB-1#TRPBF is a monostable multivibrator from the TimerBlox family, housed in a 6-lead 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 125°C. The device generates output pulses with widths programmable from 1µs to 33.6 seconds using a single external resistor and internal divider settings. It features rising-edge triggering without retrigger capability, CMOS outputs capable of sourcing or sinking 20mA, and a typical idle supply current as low as 60µA.

Multivibrators Feature Summary

• Generates precise monostable output pulses triggered by rising edges
• Configurable pulse width via single resistor and internal clock divider
• CMOS output driver supports high current loads up to 20mA
• Operates reliably across extended industrial temperature ranges

Multivibrators Applications

• Watchdog timer circuits
• Missing pulse detection systems
• Envelope detectors for signal processing
• Frequency discriminators

Multivibrators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the HDCB designation corresponds to the 6-lead DFN package variant. Ensure the -1 suffix matches the required non-retriggerable rising-edge trigger configuration. Cross-reference the full part number against the manufacturer's latest order information to confirm availability and lead times.

Multivibrators Selection Notes

Select this component when a non-retriggerable one-shot response to rising edges is required. The H-grade version is necessary for applications operating above 85°C. Verify that the required pulse width falls within the 1µs to 33.6s range. Consider the DIV pin programming requirements for setting the specific time base multiplier.

Multivibrators Part Context

This device belongs to the Analog Devices TimerBlox family of silicon timing solutions. It serves as a versatile alternative to discrete transistor-based monostable circuits. The LTC6993 series includes variants with different trigger polarities and retrigger capabilities, allowing designers to select the exact logic behavior needed for their specific timing application.

Multivibrators Replacement Considerations

Direct substitutes include other LTC6993 variants such as LTC6993IDCB-1#TRPBF for commercial temperature grades. For retriggerable functionality, consider the LTC6993IDCB-2#TRPBF. Alternative packages like SOT-23 are available under the HS6 or IS6 designations.
