1. Valid for ambient operating temperature: TA = –40°C to +85°C; VCC = 0.8 V to 5.5 V (except where noted).

2. 10k ohm (typ) internal pull-up resistor.

3. The leakage current measured on the RST pin is tested with the reset de-asserted (output high impedance).

4. Other reset threshold voltages are offered. Minimum order quantities may apply. Contact local sales office for availability.

5. Other tREC time-out periods are offered. Minimum order quantities may apply. Contact local sales office for availability.
