LTC6993IS6-1#TRMPBF

Multivibrators Overview

The LTC6993IS6-1#TRMPBF 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 programmable output pulses with widths between 1µs and 33.6 seconds, determined by a master oscillator frequency set via RSET and an internal clock divider NDIV. Key electrical parameters include a maximum propagation delay of 11ns at 5.5V, a typical idle supply current of 70µA at 10µs pulse width, and a CMOS output driver capable of sourcing or sinking up to 20mA.

Multivibrators Feature Summary

• Generates precise one-shot output pulses initiated by rising-edge trigger signals
• Configurable for positive or negative output pulse polarity via DIV pin
• Non-retriggerable architecture ignores subsequent triggers until pulse termination
• Low power consumption suitable for battery-operated applications

Multivibrators Applications

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

Multivibrators Procurement Notes

Verify the specific suffix #TRMPBF indicates mini tape and reel packaging when ordering. Confirm the IS6 designation corresponds to the industrial temperature grade (-40°C to +85°C) and TSOT-23 package. Ensure compatibility with the required trigger polarity (rising edge) as this variant does not support retriggering. Check for automotive qualified versions if AEC-Q100 compliance is necessary for the target application environment.

Multivibrators Selection Notes

Select this component when a non-retriggerable one-shot function is required with rising-edge sensitivity. Compare against LTC6993-2 if retrigger capability is needed, or LTC6993-3/4 if falling-edge triggering is preferred. Consider the H or MP grades for extended temperature ranges beyond the industrial limit. Evaluate the DIV pin resistor network requirements to achieve the desired pulse width multiplier and output polarity settings within the specified accuracy constraints.

Multivibrators Part Context

This part belongs to the Analog Devices TimerBlox family of silicon timing devices, specifically the LTC6993 series. It shares functional similarities with other variants in the family that differ primarily in trigger polarity and retriggerability. The IS6-1 suffix identifies it as the industrial grade version in a TSOT-23 package configured for non-retriggerable rising-edge operation.

Multivibrators Replacement Considerations

LTC6993IS6-2#TRMPBF: Same package and temperature grade but supports retriggering.

Multivibrators FAQ

Does the LTC6993IS6-1 support retriggering?

No, the LTC6993-1 variant is non-retriggerable and will ignore additional trigger inputs until the output pulse has terminated.

What determines the output pulse width?

The pulse width is determined by the master oscillator frequency set by RSET and the internal clock divider NDIV, which is programmed via the DIV pin voltage.
