Product details

8-bit bus transceiver for mixed-voltage systems

The 20-TSSOP package keeps the board footprint compact for dense backplane or mezzanine layouts.

Supply voltage and temperature — the design envelope

Rated for 2V to 5.5V supply, the SN74LV245APWR operates cleanly at 3.3V, which is the most common single-rail voltage for mixed-signal and MCU-based designs.

For dual-sourcing resilience, the 74LVTH16245ADGVR offers a 2.7V to 3.6V supply and 32mA drive but operates only to 85°C — check the temperature grade if your environment exceeds that.

Frequently asked questions

Can SN74LV245APWR be used at 3.3V supply?

Yes, the SN74LV245APWR operates from 2V to 5.5V, so 3.3V is well within the rated range. The 16mA output drive is maintained across the full supply range.

What is a direct replacement or equivalent for SN74LV245APWR?

The SN74LVTH16245ADGVR is a functional equivalent from the same TI family, offering 32mA drive and a 2.7V to 3.6V supply, but its temperature range is limited to -40°C to 85°C. For full industrial temp, the SN74LV245APWR remains the better fit.

What is the difference between SN74LV245APWR and SN74LVC245APWR?

The SN74LVC245APWR operates from 1.65V to 3.6V and offers 24mA drive, while the SN74LV245APWR covers 2V to 5.5V with 16mA drive. The LVC variant is optimized for lower-voltage systems; the LV variant supports 5V legacy buses.
