It packs four independent receivers into a single 16-pin DIP package, making it a compact choice for multi-drop bus interfaces where you need to listen to multiple nodes without dedicating separate ICs per channel. Each receiver converts a differential bus signal into a single-ended logic output, with a typical input hysteresis of 45 mV to reject noise on long cable runs. The supply range is 4.75 V to 5.25 V, so it runs directly off a standard 5 V rail without an extra regulator. ## Supply rail and noise margin for bus interfaces The 4.75 V to 5.25 V supply range means the part stays within spec even if your 5 V rail droops by 250 mV under load — common on long backplanes or daisy-chained bus boards. The 45 mV hysteresis is the key number for signal integrity: it sets the dead band where the receiver ignores small fluctuations on the differential pair, so a 100-metre RS-485 run at 115 kbps stays clean without external filtering. Compared to a part like the SN75LBC176 (a single transceiver), the SN75LBC175N is purely a receiver — no driver on chip. That matters if your bus topology is receive-only (e.g., a monitoring node that never transmits) or if you already have a separate driver elsewhere on the board. ## Active production — sourcing through distribution The part ships in a tube (the standard through-hole DIP format), and the 16-DIP package is widely stocked.","metaTitle":"SN75LBC175N Quad RS-422/RS-485 Receiver – TI 16-DIP","metaDescription":"SN75LBC175N quad RS-422/RS-485 receiver from Texas Instruments. 4.75V–5.25V supply, 45 mV hysteresis, 0°C–70°C, 16-DIP.

It is a quad receiver, so it handles the receive side of a differential bus for any of those standards. For RS-485 you still need a separate driver (like the SN75LBC176) if your node also transmits."},{"question":"Can SN75LBC175N be used as a replacement for SN75LBC176?","answer":"No — the SN75LBC176 is a single transceiver (driver + receiver), while the SN75LBC175N is a quad receiver with no driver. They are not pin-compatible and serve different roles on the bus. If you need a receiver-only replacement for a failed SN75LBC176, you would also need to add a separate driver elsewhere."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN75LBC175N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN75LBC175N when reusing this data.
