.Data Sheet.in Electrical Specifications Subject to Change LTC6994-1/LTC6994-2 Timer Blox: Delay Block/ Debouncer Features n n n n n n n n n n Description The LTC®6994 is a programmable delay block with a range of 1µs to 33.6 seconds. The LTC6994 is part of the Timer Blox™ family of versatile silicon timing devices. A single resistor, RSET , programs the LTC6994’s internal master oscillator frequency. 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: t DELAY = NDIV - RSET - 1µs, NDIV = 1, 8, 64,...,221 50kΩ Delay Range: 1µs to 33.6 Seconds Configured with 1 to 3 Resistors Delay Max Error: - <2.3% for Delay > 512µs - <3.4% for Delay of 8µs to 512µs - <5.1% for Delay of 1µs to 8µs Delay One or Both Rising/Falling Edges 2.25V to 5.5V Single Supply Operation 70µA Supply Current at 10µs Delay 500µs Start-Up Time CMOS Output Driver Sources/Sinks 20m A - 40°C to 125°C Operating Temperature Range Available in Low Profile (1mm) SOT-23 (Thin SOT™) and 2mm × 3mm DFN Applications n n n n n 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.
