Description

Ground.

RESET output remains low while VCC is below the reset voltage threshold, and for at least

140msec min. after VCC rises above reset threshold.

RESET output remains high while VCC is below the reset voltage threshold, and for at least

140msec min. after VCC rises above reset threshold.

Manual reset input generates a reset when MR is below VIL.

Supply voltage.
