They provide excellent circuit reliability and low cost. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, with hysteresis keeping it asserted for time delay determined by externally pro- grammable time delay generator after VCC has risen above the reset threshold. The G657L has an open-drain output stage, while the G656 have push-pull outputs. The G657L’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The G656L has an active-low RESET output, while the G656H has an active-high RESET output. The outputs are guaranteed to be in the correct logic state for VCC down to 0.8V. The G656/G657 are available in 5-pin TSOT-23-5 package.
