The inverting logic means the output is the complement of the input — a detail that matters if you are replacing a non-inverting part and the firmware expects active-high enables.","metaTitle":"SN74AHC240DW 74AHC Buffer, Inverting, 2V-5.5V, 20-SOIC","metaDescription":"Texas Instruments SN74AHC240DW octal inverting buffer with 3-state outputs, 2V to 5.5V supply, 8mA drive, -40°C to 85°C.

For a 5V TTL bus the AHCT is the drop-in; for a pure CMOS or 3.3V rail the AHC is the correct choice.
