TimerBlox: Delay Block/
Debouncer
The LT C
®
6994 is a programmable delay block with a
range of 1µs to 33.6 seconds. The LTC6994 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 LTC6994’s time base. The
input-to-output delay is determined by this master oscil-
lator and an internal clock divider, N
DIV
, programmable
to eight settings from 1 to 2

The output (OUT) follows the input (IN) after delaying
the rising and/or falling transitions. The LTC6994-1 will
delay the rising or falling edge. The LTC6994-2 will delay
both transitions, and adds the option to invert the output.

LTC6994-1
or
LTC6994-2 or
The LTC6994 also offers the ability to dynamically adjust
the delay time via a separate control voltage.
For easy configuration of the LTC6994, download the
TimerBlox Designer tool at www.linear.com/timerblox.
