ncp1232dr2 ON Semiconductor, ncp1232dr2 Datasheet - Page 3

• Manufacturer Part Number: ncp1232dr2
• Description: Microprocessor Monitor
• Manufacturer: ON Semiconductor

*Stresses beyond those listed under “Absolute Maximum Ratings’’ may cause permanent damage to the device. These are stress ratings only,
1. PB RST is internally pulled up to V CC with an internal impedance of typically 40 kΩ.
2. Measured with outputs open.
3. All voltages references to GND.
4. Guaranteed by design.
5. PB RST must be held low for a minimum of 20 msec to guarantee a reset.
6. t R = 5 µsec.
