DESCRIPTION

TimerBlox: Delay Block/

Debouncer

The LTC®6994 is a programmable delay block with a

range of 1µs to 33.6 seconds. The LTC6994 is part of

cillator frequency, setting the LTC6994’s time base. The

input-to-output delay is determined by this master oscil-

50kΩ

21

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.

The LTC6994 also offers the ability to dynamically adjust

the delay time via a separate control voltage.
