The LTC®6993 is a monostable multivibrator (also known as a “one-shot” pulse generator) with a programmable pulse width of 1µs to 33.6 seconds. The LTC6993 is part of the Timer Blox® family of versatile silicon timing devices. A single resistor, RSET, programs an internal master oscillator frequency, setting the LTC6993’s time base. The output pulse width is determined by this master oscillator and an internal clock divider, settings from 1 to 221. NDIV , programmable to eight t OUT = NDIV - RSET 50kΩ - 1µs, NDIV = 1, 8, 64,...,221 The output pulse is initiated by a transition on the trigger input (TRIG). Each part can be configured to generate positive or negative output pulses. The LTC6993 is available in four versions to provide different trigger signal polarity and retrigger capability.
