TimerBlox: Monostable
Pulse Generator (One Shot)
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 LTC699
3’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
21
.

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
.
DEVICE INPUT POLARITY RETRIGGER
LTC6993-1 Rising-Edge No
LTC6993-2 Rising-Edge Yes
LTC6993-3 Falling-Edge No
LTC6993-4 Falling-Edge Yes
The LTC6993 also offers the ability to dynamically adjust
the width of the output pulse via a separate control voltage.
For easy configuration of the LTC6993, download the
TimerBlox Designer tool at www.linear.com/timerblox.
