Bus transceiver for mixed-voltage backplanes
The SN74LVC543APW: It operates from a 1.65V to 3.6V supply. The device provides 24mA source and sink drive on each output.
The 1.65V to 3.6V supply range covers the common 1.8V and 3.3V rails used in modern FPGAs, SoCs, and low-power ASICs.
It is fully RoHS3 compliant, with no exemptions that would complicate EU or UKCA declarations. For production BOMs that require a dual-source option, the 74LVC family has broad socket compatibility across other 74-series transceivers, though pin-for-pin substitution should be verified against the 24-TSSOP footprint.
