The 24-TSSOP package keeps the board footprint small for dense layouts. ## Supply rail and drive strength — what they mean on the board At 3.0 V it still meets the full drive specs, which matters in battery-backed or lightly loaded supplies. The 32 mA high-level and 64 mA low-level output currents are asymmetric — the stronger sink handles the higher capacitive load on the falling edge, common on long traces or multi-drop buses. If you are driving more than eight loads per bit, check the DC fan-out against the input current of the receivers; the 64 mA sink can handle about 20 LSTTL loads at 3.3 V. ## Temperature grade and deployment No special thermal management is needed at the rated drive levels. ## Lifecycle and sourcing The 74LVTH162245 (SN74LVTH16245ADGVR) is a 16-bit dual-element part in the same family, useful when you need two bytes in one package.","metaTitle":"SN74LVTH543PW 74LVTH Transceiver, 2.7V–3.6V, 24-TSSOP","metaDescription":"TI SN74LVTH543PW 8-bit non-inverting transceiver with 3-state outputs. 2.7V–3.6V supply, 32mA/64mA drive, -40°C to 85°C.
