Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The G670/G671 are microprocessor (P) supervisory circuits used to monitor the power supplies in P and digital systems. G670/G671 provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V- powered circuits.

These circuits of G670/G671 perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The G671L has an open-drain output stage, while the G670 have push-pull outputs. The G671L's open-drain SET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The G670L have an active-low RESET output, while the G670H has an active-high RESET output. The reset comparator is designed to ignore fast transients on VCC,and the outputs are guaranteed to be in the correct logic state for VCC down to 1V. Low supply current makes the G670.
