TimerBlox: Monostable  
Pulse Generator (One Shot)  
FEATURES  
DESCRIPTION  
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  
oftheTimerBlox® familyofversatilesilicontimingdevices.  
n
Pulse Width Range: 1µs to 33.6 Seconds  
n
Configured with 1 to 3 Resistors  
n
Pulse Width Max Error:  
– <2.3% for Pulse Width > 512µs  
– <3.4% for Pulse Width of 8µs to 512µs  
– <4.9% for Pulse Width of 1µs to 8µs  
Four LTC6993 Options Available:  
A single resistor, R , programs an internal master os-  
SET  
cillator frequency, setting the LTC6993’s time base. The  
output pulse width is determined by this master oscillator

– Rising-Edge or Falling-Edge Trigger  
– Retriggerable or Non-Retriggerable  
and an internal clock divider, N , programmable to eight

in four versions to provide different trigger signal polarity  
and retrigger capability.
