General Description
The NE56610/11/12 series is a family of devices designed to generate a reset signal for a
variety of microprocessor and logic systems. Accurate reset signals are generated during
momentary power interruptions or when ever power supply voltages sag to intolerable levels.
The NE56610/11/12 incorporates an internal timer to provide reset delay and ensure proper
operating voltage has been attained. In addition, a manual reset pin is available. An Open
Collector output topology is incorporated to provide adaptability for a wide variety of logic and
microprocessor systems.
NE56610/11/12 is available in the TSSOP5 surface mount package.
