Pin Functions

PIN I/O DESCRIPTION
NAME D, P, PS, PW, JG FK
NO.
CONT 5 12 I/O Controls comparator thresholds, Outputs 2/3 VCC, allows bypass capacitor connection
DISCH 7 17 O Open collector output to discharge timing capacitor
GND 1 2 – Ground
NC 1, 3, 4, 6, 8, 9, 11, 13, 14, 16, 18, 19 – No internal connection
OUT 3 7 O High current timer output signal
RESET 4 10 I Active low reset input forces output and discharge low.
THRES 6 15 I End of timing input. THRES > CONT sets output low and discharge low
TRIG 2 5 I Start of timing input. TRIG < ½ CONT sets output high and discharge open
VCC 8 20 – Input supply voltage, 4.5 V to 16 V. (SE555 maximum is 18 V)
