Product details

1.65V–3.6V supply — the mixed-voltage bus bridge

That voltage range is the headline decision: it directly answers whether this part works with 1.8V logic (yes) and 3.3V logic (yes), without needing a separate level shifter.

Industrial temp and active lifecycle

ROHS3 compliant, no exemption issues for EU markets.

20-SOIC footprint — board-level fit

The wide SOIC body gives good visual inspection access and hand-solderability for prototyping, while still being pick-and-place friendly for production.

Frequently asked questions

Is SN74ALVC245DW compatible with 1.8V logic?

Yes. The supply voltage range of 1.65V to 3.6V means the part operates at 1.8V nominal. Input and output thresholds track the supply rail, so it interfaces directly with 1.8V logic families without external level translation.

What is the equivalent of SN74ALVC245DW?

The closest functional peer in the same 8-bit non-inverting transceiver class is the SN74ABT2245DW, but note the supply voltage difference: the ABT part requires a 4.5V minimum supply, making it incompatible with 1.8V or 2.5V systems. For 3.3V-only designs the ABT variant is a drop-in alternative; for mixed-voltage buses the ALVC is the correct choice.
