The LTC6994 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, RSET, programs an internal master oscillator frequency, setting the LTC6994’s time base. The input-to-output delay is determined by this master oscillator and an internal clock divider, NDIV, programmable to eight settings from 1 to 221.

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.

Applications

  • Noise Discriminators/Pulse Qualifiers
  • Delay Matching
  • Switch Debouncing
  • High Vibration, High Acceleration Environments
  • Portable and Battery-Powered Equipment
