LTC6994HDCB-2#TRMPBF

LTC6994-2 is a TimerBlox delay block/debouncer. It is a programmable delay block with a range of 1µs to 33.6 seconds. This part of the TimerBlox® family of versatile silicon timing devices. A single resistor, RSET, programs an internal host oscillator frequency, setting the LTC6994’s time base. The output (OUT) follows the input (IN) after delaying the rising and/or falling transitions. This will delay both transitions, and adds the option to invert the output. Application includes noise discriminators/pulse qualifiers, delay matching, switch debouncing, high vibration, high acceleration environments, portable and battery-powered equipment.
