The non-inverting transceiver architecture means data flows from A to B (or B to A) with the same logic polarity — no inversion to account for in the firmware or FPGA logic. ROHS3 compliant — no exemptions for lead in solder, so it passes the EU RoHS directive without a certificate-of-exemption chase.","metaTitle":"SN74AHC245QWRKSRQ1 Octal Bus Transceiver, 2-5.5V, AEC-Q100","metaDescription":"SN74AHC245QWRKSRQ1 automotive octal bus transceiver, 2V-5.5V supply, 8mA drive, 20-VQFN with wettable flank.
