NE56605-42 is a system reset circuit with built-in watchdog timer, which can generate accurate reset signals during momentary power interruptions or when power supply voltages sag to intolerable levels. It can monitor the operation of microprocessors and terminate abnormal system operations caused by microprocessor malfunctions by generating a system reset through the watchdog. The product has a watchdog monitoring time of 10 ms, can trigger reset with VCC down to 0.8 VDC, and requires few external components.
The NE56605-42 is a system‑reset integrated circuit with a built‑in watchdog timer designed to generate reset signals for microprocessor and logic systems when power drops or the processor malfunctions.
The device is supplied in an SO8 plastic small‑outline package, operates from 0.3 V to 10 V, provides both positive and negative logic reset outputs, and includes specifications such as a typical 10 ms watchdog monitoring time, 250 mW maximum power dissipation, and an operating temperature range of –20 °C to 70 °C.
