The 20-TSSOP package suits surface-mount assembly on dense PCBs. The 7.8mA output current is typical for HC-family parts — enough to drive a few CMOS inputs or a short trace, but not a 50Ω backplane. If you need more fan-out, look at the ABT or LVT families. ## Industrial temperature and 3-state control The 3-state outputs allow multiple buffers to share a data bus — the output enable pin disables all eight channels, putting them in high-impedance. ROHS3 compliant. No official successor or second-source alternate is listed; the part is sole-sourced from Texas Instruments.","metaTitle":"SN74HC240PW Buffer, Inverting, 3-State, 20-TSSOP, 2V-6V","metaDescription":"SN74HC240PW from Texas Instruments is an active 74HC inverting buffer with 3-state outputs.
