• Manufacturer Part Number: lm3722im5x-4.63
• Description: 5-pin Microprocessor Reset Circuits
• Manufacturer: National Semiconductor Corporation

Symbol
Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which the device operates
correctly. Operating ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical
Characteristics.
Note 2: The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
Note 3: At elevated temperatures, devices must be derated based on package thermal resistance. The device in the SOT23-5 package must be derated at 4.5mW/
°C at ambient temperatures above 70°C. The device has internal thermal protection.
Note 4: Production testing done at T
(SQC) methods.
Note 5: RESET Output for LM3722 and LM3724, RESET output for LM3723.
Note 6: Glitches of 100 ns or less typically will not generate a reset pulse.
