Surface-mount assembly follows standard QFN profiles: a 0.18 mm stencil aperture for the exposed pad and 0.25 mm for the peripheral lands. ## Supply-voltage flexibility and decoupling The choice affects the output swing and noise margin on the serial bus; 3.3 V operation gives a wider logic-high threshold at the expense of slightly higher dynamic power. The exposed paddle acts as the ground return — connect it directly to the ground plane with multiple vias to keep the inductance below 1 nH. ## Lifecycle and compliance status The part is ROHS3 Compliant, meeting the latest EU restriction-of-hazardous-substances directive without exemptions.","metaTitle":"DS32EV400SQ/NOPB TI Interface IC, 48-WQFN, 2.5V/3.3V","metaDescription":"Texas Instruments DS32EV400SQ/NOPB specialized interface IC for signal processing.
