Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 5. Tested according to TIA/EIA-485-A, Section 4.2.6 (±60V for 15µs at a 1% duty cycle). 6. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details. 7. For θJC, the “case temp” location is taken at the package top center. Electrical Specifications Test Conditions: VCC = 3V to 3.6V and 4.5V to 5.5V; Unless Otherwise Specified. Typicals are at the worst case of VCC =5V or VCC =3.3V, TA = +25°C (Note 8). Boldface limits apply over the operating temperature range, -40°C to +85°C.
