(2) VCCO is the VCC associated with the output port. (3) All unused data inputs of the device must be held at VCCI or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, SCBA004. (4) For VCCI values not specified in the data sheet, VIH min = VCCI × 0.7 V, VIL max = VCCI × 0.3 V. (5) For VCCA values not specified in the data sheet, VIH min = VCCA × 0.7 V, VIL max = VCCA × 0.3 V. 7.4 Thermal Information SN74AVCH16T245 TSSOP TVSOP ZQL/GQL THERMAL METRIC(1) UNIT (DGG) (DGV) (BGA MICROSTAR JUNIOR) 48 PINS 48 PINS 56 PINS RθJA Junction-to-ambient thermal resistance 82.5 69.9 64.6 °C/W RθJC(top) Junction-to-case (top) thermal resistance 34.2 23.9 16.6 °C/W RθJB Junction-to-board thermal resistance 45.1 36.6 30.8 °C/W ψJT Junction-to-top characterization parameter 2.7 1.7 0.9 °C/W ψJB Junction-to-board characterization parameter 44.6 36.2 64.6 °C/W (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953. 6 Submit Documentation Feedback Copyright © 2004–2015, Texas Instruments Incorporated Product Folder Links: SN74AVCH16T245 |
