These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltages are with respect to Ground. Currents are positive into, negative out of the specified pin. Consult packaging section of databook for thermal/imitations and considerations of package. 6.2 Handling Ratings MIN MAX UNIT Tstg Storage temperature range -65 150 °C 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT TJ Operating junction temperature -55 125 °C 6.4 Thermal Information (1) UC1856-SP THERMAL METRIC(2) UNIT 16 PIN RθJC(bottom) J package 7.3 °C/W HKT package 2.9 (1) HKT: Computational fluid dynamics (CFD) model of 16 pin HKT package to Mil Std 883 Method 1012.1 standard. 16/J: Curve based on CFD models correlated to available physical measurement data points.
