Output drive is rated 32 mA source and 64 mA sink, enough to drive a heavily loaded parallel bus or a bank of LED indicators through a series resistor. The asymmetric sink strength is typical for bipolar CMOS (BiCMOS) output stages in the 74LVTH series — the extra sink current handles capacitive discharge on falling edges. ## 20-TSSOP footprint — layout and thermal The 20-TSSOP package (0.173\" body width, 4.40 mm) is a standard fine-pitch SOIC footprint. The 0.65 mm lead pitch routes easily on two-layer boards with 8/8 mil trace/space rules. No thermal pad or exposed paddle — junction-to-ambient thermal resistance is package-limited, so keep the ambient under 85°C for full drive current. No lead, no halogens in the molding compound.","metaTitle":"SN74LVTH245APWR 3.3V Bus Transceiver, 20-TSSOP, 32/64mA","metaDescription":"TI SN74LVTH245APWR non-inverting transceiver, 2.7V–3.6V supply, 32mA source / 64mA sink, 20-TSSOP.
