Description
RESET output remains low while V_CC is below the reset voltage threshold, and
for 200 ms (100 ms minimum) after V_CC rises above reset threshold. The output
stage of the TC1275 is complimentary. The output stage of the TC1276 is open-
drain.
RESET output remains high while V_CC is below the reset voltage threshold, and
for 200 ms (100 ms minimum) after V_CC rises above reset threshold. The output
stage of the TC1277 is complimentary.
Supply voltage (1.2V to 5.5V TC1275 and TC1276, 1.8V to 5.5V TC1277).
