One or two 120Ω Terminations CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 5. One output at a time, IOUT ≤100mA for ≤10 mins. 6. JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech Brief TB379. 7. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details. 8. For JC, the “case temp” location is the center of the exposed metal pad on the package underside. 9. For JC, the “case temp” location is taken at the package top center. Electrical Specifications Test Conditions: VCC = 3.15V to 3.45V, C1 - C4 = 0.1µF; unless otherwise specified. Typicals are at VCC = 3.3V, TA = +25°C (Note 10). Boldface limits apply across the operating temperature range, -40°C to +85°C.
