Pin Functions

PIN I/O DESCRIPTION
NAME NO.
LM809 LM810
RESET 2 — O Active-low output. RESET remains low while VCC is below the reset threshold, and for 240 ms after VCC rises above the reset threshold.
RESET — 2 O Active-high output. RESET remains high while VCC is below the reset threshold, and for 240 ms after VCC rises above the reset threshold.
VCC 3 3 I Supply voltage
GND 1 1 — Ground reference
