TimerBlox: Delay Block/

Debouncer

FEATURES

DESCRIPTION

The LTC^®6994 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.

Delay Range: 1µs to 33.6 Seconds

Configured with 1 to 3 Resistors

Delay Max Error:

– <2.3% for Delay > 512µs

A single resistor, R , programs an internal master os-

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

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.

Available in Low Profile (1mm) SOT-23 (ThinSOT™)

and 2mm × 3mm DFN
