Linear Technology LTC6994CDCB-2#TRPBF
- Part Number:
- LTC6994CDCB-2#TRPBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 2982587-LTC6994CDCB-2#TRPBF
- Description:
- IC DELAY LINE 8TAP PROG 6DFN
- Datasheet:
- LTC6994CDCB-2#TRPBF
Description
The LTC6994 is a programmable delay block with a range of 1us to 33.6 seconds. It 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, Noiv, programmable to eight settings from 1 to 221:
DELAY = DIVSET 1μs, NDIV = 1, 8, 64...2150k≤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.
The LTC6994 also offers the ability to dynamically adjust the delay time via a separate control voltage.
