LTC6993HDCB-3#TRPBF

Multivibrators Overview

The LTC6993HDCB-3#TRPBF is a monostable multivibrator from the TimerBlox family, manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.25V to 5.5V and features a programmable output pulse width spanning from 1µs to 33.6 seconds. The device utilizes a master oscillator controlled by an external resistor (RSET) and an internal clock divider (NDIV) for timing precision. This specific variant supports falling-edge triggering without retrigger capability and is housed in a 6-lead Plastic DFN package with an operating temperature range of –40°C to 125°C.

Multivibrators Feature Summary

• Programmable pulse width generation via external resistor and internal divider settings
• Falling-edge trigger input sensitivity for non-retriggerable operation
• Configurable output polarity through DIV pin voltage selection
• Low supply current consumption suitable for battery-powered applications

Multivibrators Applications
