The single-element, 8-bit-per-element architecture means one package replaces eight discrete inverters, saving board area and BOM line count. ## Industrial temperature grade — where it runs The 74HC series CMOS process keeps quiescent current low across the temperature range, so the buffer doesn't add a thermal load to the board.","metaTitle":"SN74HC540PWR Buffer, Inverting, 3-State, 20-TSSOP, 2V-6V","metaDescription":"Texas Instruments SN74HC540PWR 74HC series inverting buffer with 3-state outputs. 2V-6V supply, 7.8mA drive, -40°C to 85°C, 20-TSSOP.
