That confines it to indoor, climate-controlled equipment — office networking, test racks, or control cabinets with HVAC. Not for unheated enclosures, engine bays, or outdoor telecom pedestals. ## Sourcing reality — active, no LTB pressure The SN75178BP is listed as Active with ROHS3 compliance. No last-time-buy notice, no NRND flag. That means it is still a standard production part — you are not hunting surplus or paying a premium for end-of-life stock. The Tube package is the factory-shipping format; if your pick-and-place line needs Tape & Reel, confirm with your supplier that the reeled variant is the correct alternate. ## Pinout and full-duplex support — what the evidence says The SN75178BP is a single-channel ReDriver. For RS485 full-duplex operation you need two channels — one for the transmit pair and one for the receive pair. This part handles one differential path. If your application requires simultaneous bidirectional repeat, you need two SN75178BP devices or a dual-channel part.","metaTitle":"SN75178BP RS422/RS485 ReDriver, 19ns, 8-PDIP","metaDescription":"TI SN75178BP is a single-channel RS422/RS485 ReDriver in 8-PDIP. 5V supply, 19 ns delay, 0–70°C.
