68HC11 /双向兼容的微处理器复位电路 68HC11/Bidirectional-Compatible レP Reset Circuit
General Description
The MAX6314 low-power CMOS microprocessor µP supervisory circuit is designed to monitor power supplies in µP and digital systems. The MAX6314’s RESET output is bidirectional, allowing it to be directly connected to µPs with bidirectional reset inputs, such as the 68HC11. It provides excellent circuit reliability and low cost by eliminating external components and adjustments. The MAX6314 also provides a debounced manual reset input.
