NE56610/11/12-XX

GENERAL DESCRIPTION

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.
