LTC6994-1/LTC6994-2 TimerBlox: Delay Block/ Debouncer 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.
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 oscil- lator and an internal clock divider, NDIV , programmable to eight settings from 1 to 221: tDELAY = NDIV • RSET 50kΩ • 1µs, NDIV = 1, 8, 64,.
.
.
,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.
DEVICE DELAY FUNCTION LTC6994-1 or LTC6994-2 or The LTC6994 also offers the ability to dynamically adjust the delay time via a separate control voltage.
For easy configuration of the LTC6994, use the TimerBlox LTC6994: Delay Web-Based Design Tool.
