(1) Stresses beyond those listed under
Absolute Maximum Ratings may cause permanent damage to the device. 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 voltage values are with respect to GND and are at the device not at the power supply.
(3) Applies to external input and bidirectional buffers.
(4) TI strongly recommends I/O simulations (using IBIS models) for operation near the extremes of the supported ambient operating temperature range to ensure that the PCB design provides acceptable signal integrity.
(5) The operating ambient temperature range assumes zero forced air flow, a JEDEC JESD51 junction-to-ambient thermal resistance value at zero forced air flow (R
θJA at 0 m/s), a JEDEC JESD51 standard test card and environment, along with minimum and maximum estimated power dissipation across process, voltage, and temperature. Thermal conditions vary by application, which impacts R
θJA. Thus, maximum operating ambient temperature varies by application.
- TA_min = TJ_min – (PD_min × RθJA) = –30°C – (0.0 W × 64.96°C/W) = –30°C
- TA_min = TJ_min – (PD_min × RθJA) = 105°C – (0.3 W × 64.96°C/W) = 85°C
