SA56614-XX
GENERAL DESCRIPTION
The SA56614-XX is a CMOS device designed to generate a reset signal for a variety of microprocessor and logic systems. Accurate reset signals are generated during momentary power interruptions, or whenever power supply voltages sag to intolerable levels. Several reset threshold versions of the device are available. A totem-pole output topology is incorporated to provide both current source and sink capability to the user. SA56614-XX is available in the SOT23-5 surface mount package.
FEATURES
12 VDC maximum operating voltage Low operating voltage (0.65 V) Totem pole CMOS output Offered in reset thresholds of Available in SOT23-5 surface mount package
