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
of the TimerBlox
®
family of versatile silicon timing devices.
A single resistor, R
SET
, programs an internal master os-
cillator frequency, setting the LTC6993’s time base. The
output pulse width is determined by this master oscillator
and an internal clock divider, N
DIV
, programmable to eight
settings from 1 to 2

3mm DFN
The output pulse is initiated by a transition on the trigger
input (TRIG). Each part can be configured to generate posi-
tive or negative output pulses. The LTC6993 is available
in four versions to provide different trigger signal polarity
and retrigger capability.
