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). 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.
