Key Features
- Power-On Reset: Provides a reset signal to the microprocessor during power-up, ensuring both the power supply and microprocessor stabilize.
- Manual Reset: Equipped with a manual reset input that ignores input pulses of 100 ns or less and is guaranteed to accept input pulses of greater than 10 μs.
- Low Power Consumption: Low supply current, making it suitable for battery-powered applications.
- Stable Reset Output: The reset output remains valid even when VCC is as low as 1 V, ensuring the microprocessor remains in a stable shutdown condition during power-down.
- Noise Immunity: Designed to operate in noisy environments, the manual reset input is debounced to ignore unwanted glitches.
