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:
4. ISL32177E and ISL32277E only.
5. Excluding the ISL32177E and ISL32277E.
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. θJA 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 for details.
8. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
9. For θJC, the “case temp” location is taken at the package top center.
Electrical Specifications Test Conditions: VCC = 3.0V to 5.5V; VL = VCC (ISL32177E and ISL32277E only); Typicals are at
the worst case of VCC = 3.3V or VCC = 5V, TA = +25°C; Unless Otherwise Specified. Boldface
limits apply over the operating temperature range. (Notes 10, 14)
