Product details

Supply voltage flexibility and mixed-voltage bridging

The SN74LVC541APWT: With 24 mA sink and 24 mA source capability per output, the buffer drives standard logic fan-out of 10 LSTTL loads or a bank of LED indicators directly, eliminating a separate driver stage.

20-TSSOP footprint and board integration

The 3-state outputs allow multiple buffers to share a common data bus — the OE pin pulls the outputs into high-impedance, so unused channels on the same bus do not fight each other.

Compliance and sourcing posture

ROHS3 compliant with no exemptions — the part ships without lead, mercury, cadmium, or any of the six restricted substances, clearing EU RoHS and California Proposition 65 requirements without an exemption expiry date. No minimum order quantity restriction applies.

Frequently asked questions

What is the closest functional second-source for SN74LVC541APWT?

The SN74LVC1G125YZPR is a single-bit buffer from the same 74LVC family with 32 mA output drive and the same 1.65V supply minimum, but it is a single-channel device in a different package (DSBGA). It is not a pin-compatible drop-in — the 20-TSSOP footprint of the SN74LVC541APWT requires a board spin to use the single-bit alternative.
