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 V_DC maximum operating voltage
• Low operating voltage (0.65 V)
