PinNameFunctionsNotes
1GND
GND
Ground
2TRIG
GPIO
Start of timing input. TRIG < 1/2 CONT sets output high and discharge open.
3OUT
GPIO
High current timer output signal.
4RESET
GPIO
Active low reset input forces output and discharge low.
5CONT
GPIO
Input. Controls comparator thresholds. Outputs 2/3 VDD and allows bypass capacitor connection.
6THRES
GPIO
Input. End of timing input. THRES > CONT sets output low and discharge low.
7DISCH
GPIO
Output. Open collector output to discharge timing capacitor.
8VDD
POWER
Power-supply voltage.
