It operates from a 4.5 V to 5.5 V supply. Output drive is rated at 32 mA sourcing and 64 mA sinking per channel, enough to drive heavily loaded parallel buses or long backplane traces without external line drivers. The industrial temperature range of -40°C to 85°C covers factory-floor and outdoor telecom enclosures. ## Lifecycle and sourcing The SN74ABT240APWR is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect.","metaTitle":"SN74ABT240APWR Buffer Inverting 3-State, 4.5V-5.5V, 20-TSSOP","metaDescription":"TI SN74ABT240APWR buffer/inverting 3-state, 32mA/64mA output, 4.5V-5.5V supply, -40°C to 85°C, 20-TSSOP.
