LTC6993HDCB-1#TRMPBF

Multivibrators Overview

The LTC6993HDCB-1#TRMPBF 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 master oscillator and internal divider. It features rising-edge triggering without retrigger capability, CMOS outputs sourcing/sinking up to 20mA, and low power consumption.

Multivibrators Feature Summary

• Generates precise one-shot pulses with widths adjustable via external resistor and divider settings
• Configurable for positive or negative output pulse polarity through DIV pin programming
• Includes hysteresis on trigger input to accommodate slow-rising signals
• Provides fast recovery time and dynamic pulse width adjustment capabilities

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 tape and reel mini packaging when ordering. Confirm the HDCB designation corresponds to the 6-lead DFN package variant. Ensure the temperature grade H matches the required -40°C to 125°C operational environment. Cross-reference the full part number against official Analog Devices documentation to confirm availability and manufacturing status before finalizing procurement plans.

Multivibrators Selection Notes

Select this component for applications requiring a non-retriggerable monostable response to rising-edge triggers. Choose the HDCB package for surface-mount designs needing a compact footprint. Verify that the required pulse width falls within the 1µs to 33.6s range defined by the RSET and NDIV configurations. Consider the supply current requirements relative to the chosen divider setting and load conditions.

Multivibrators Part Context

This device belongs to the LTC6993 series of silicon timing devices, which includes variants with different trigger polarities and retrigger capabilities. The -1 suffix specifically denotes the rising-edge, non-retriggerable version. It shares the same core architecture and pinout as other members of the family, differing primarily in internal logic configuration for trigger handling.

Multivibrators Replacement Considerations

Direct substitutes include other LTC6993 variants such as LTC6993IDCB-1#TRPBF for commercial temperature ranges or LTC6993IS6-1#TRMPBF for SOT-23 packaging. Ensure any replacement maintains the same trigger edge sensitivity and retrigger behavior if circuit compatibility is critical.
