Description
Ground.
RESET output remains low while V_CC is below the reset voltage threshold, and for at least
140msec min. after V_CC rises above reset threshold.
RESET output remains high while V_CC is below the reset voltage threshold, and for at least
140msec min. after V_CC rises above reset threshold.
Manual reset input generates a reset when MR is below V_IL.
Supply voltage.
