Electrical Specifications
These specifications apply for T A = -10°C to +100°C, unless otherwise stated. All typical specifications
T A = +25°C, VCC = 5V. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise
specified. Temperature limits established by characterization and are not production tested. (Continued)
