This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation
sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect
reliability.

NOTES:
1) All voltages are referenced to ground.
2) Measured with V
CC
≥
2.7V.
3) A 1kΩ external resistor may be required in some applications for proper operation of the
microprocessor reset control circuit.
4) Measured with
RST
output open.
5) t
R
= 5µs.
6) V
OH

OH
are a function of the value of R
P
and the associated output load conditions.
7) This value is for reference in defining values for t
RPD
and should not be considered a requirement for
proper operation or use of the device.
