All electrical characteristics are measured with 0.1-
F capacitors connected at REF, CT, and VCC to GND.
Full range is 0
°C to 70°C for the C-suffix devices, –40°C to 85°C for the I-suffix devices, and –40°C to 125°C for the Q-suffix device.
§ This is the lowest voltage at which RESET becomes active.
