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. The 24mA output drive at both high and low levels matches standard backplane transceiver requirements, preserving signal integrity over short ribbon cables or PCB traces. ## Lifecycle and compliance — no LTB risk, RoHS3 ready 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.","metaTitle":"SN74LVC543APW 74LVC Transceiver, Non-Inverting, 1.65V–3.6V","metaDescription":"TI SN74LVC543APW 8-bit transceiver with 3-state outputs, 24mA drive, 1.65V–3.6V supply, -40°C to 85°C, 24-TSSOP.
