Stresses beyond those listed under "Absolute Maximum Ratings" may cause p'ermanent damage to the device. These are stress rat- ings 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 G696/G697 are microprocessor (µP) supervisory  circuits used to monitor the power supplies in µP and  digital systems. G696/G697 provide excellent circuit reliability  and low cost and adjustments when used with +5V,  +3.3V, +3.0V- powered circuits.

These circuits of G696/G697 perform a single function: they assert a  reset signal whenever the V_CC supply voltage declines  below a preset threshold, with hysteresis keeping it  asserted for time delay determined by externally pro- gramable time delay generator. after V_CC has risen  above the reset threshold. Reset thresholds suitable  for operation with a variety of supply voltages are  available.

The G697L has an open-drain output stage, while the  G696 have push-pull outputs. The G697L's open-drain  RESET   output requires a pull-up resistor that can be  connected to a voltage higher than V_CC. The G696L  have an active-low  _RESET   output, while the G696H  has an active-high RESET output. The reset com-
parator is designed to ignore fast transients on V_CC,  and the outputs are guaranteed to be in the correct  logic state for V_CC down to 0.8V.

Low supply current makes the G696/G697 ideal for use in portable equipment. The G696/G697 are avail- able in 5-pin SOT23-5 packages.
