RESET (LM809)
Active-low output. RESET remains low while V
CC is below the reset threshold, and
for 240ms after V
CC rises above the reset threshold.
RESET (LM810)
Active-high output. RESET remains high while V
CC is below the reset threshold, and
for 240ms after V
CC rises above the reset threshold.
