FeaTures  
DescripTion  
The LTC®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.

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.
