8-bit bus transceiver for 3.3 V backplanes
The single-element, 8-bit architecture matches byte-wide data paths common in industrial controllers, telecom line cards, and mixed-voltage systems where the 3.3 V side needs to talk to a 5 V-tolerant bus (the LVTH inputs are 5 V-tolerant, though the supply rail stays at 3.3 V).
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.
No special thermal management is needed at the rated drive levels.
The 74LVTH162245 (SN74LVTH16245ADGVR) is a 16-bit dual-element part in the same family, useful when you need two bytes in one package.
