The symmetrical 24mA output drive (both high and low) is enough to fan out to ten standard LSTTL loads or drive a short ribbon cable, but not intended for heavy capacitive loads like long backplanes. The 74AC family's CMOS inputs have good noise immunity across this range, though the 3-state outputs need pull-up or pull-down resistors on the enable lines if the bus floats during power sequencing. The ROHS3 rating covers the full substance restriction list, so it qualifies for new designs targeting EU and global markets without exemption tracking.","metaTitle":"SN74AC240DWR 74AC Octal Inverting Buffer, 2V-6V, 20-SOIC","metaDescription":"Texas Instruments SN74AC240DWR 74AC-series octal buffer/inverter with 3-state outputs. 2V-6V supply, 24mA drive, -40°C to 85°C.
