The NE56610/11/12-XX 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 (M/R) is available. An Open
Collector output topology provides adaptability for a wide variety of
logic and microprocessor systems.
NE56610/11/12 is available in the 5-lead small outline surface mount
package (SOP003.
