It buffers and directs bidirectional data between two buses (A and B ports), with a direction control (DIR) and an output-enable (OE) that puts all outputs into high-impedance state. The 2V to 6V supply range lets it ride on 3.3V or 5V rails without a regulator — handy for mixed-voltage boards in industrial control panels, PLC I/O modules, and telecom line cards. The industrial temperature grade (-40°C to 85°C) means it stays rated for factory-floor enclosures and outdoor cabinets, not just office gear. ## 7.8 mA output drive — what it means for your bus Each output sources or sinks 7.8 mA (both high and low). That's standard for 74HC — enough to drive a handful of CMOS inputs or a few LED indicators, but not a backplane with long traces or multiple TTL loads. ## Lifecycle and compliance The SN74HC245NS is listed as Active with ROHS3 compliance. No end-of-life notice, no last-time-buy window. TI still runs this part through normal production, so you can spec it into a new BOM without worrying about a sudden LTB. The 20-SO package (0.209\" body width, 5.30 mm) is a standard footprint shared across many 74HC and 74HCT transceivers, making it straightforward to dual-source if needed.","metaTitle":"SN74HC245NS 74HC Transceiver, Non-Inverting, 20-SOIC, 2V-6V","metaDescription":"TI SN74HC245NS 8-bit non-inverting transceiver with 3-state outputs. 74HC series, 2V-6V supply, -40°C to 85°C, 20-SOIC.
