It operates from a 4.75 V to 5.25 V supply rail and includes 45 mV of receiver hysteresis for noise immunity on long bus runs. With 9 drivers and 9 receivers, this transceiver can serve a multi-drop RS-485 network with up to 9 nodes, or handle bidirectional RS-422 links across 9 separate channels — reducing component count compared to using individual transceivers per channel. The 45 mV receiver hysteresis filters out noise on the differential bus, which is critical when running cables through electrically noisy industrial or automotive environments. The 56-TSSOP package (0.240-inch body width, 6.10 mm) is a surface-mount footprint that requires a 4-layer PCB for proper fan-out of the 56 pins — plan your board stack-up accordingly. ## Lifecycle and sourcing posture Current pricing and lead time are confirmed at quote time — submit an RFQ with your target quantity and we will source against your BOM line.","metaTitle":"SN75976A1MDGGREP RS485/RS422 Transceiver 56TSSOP - Texas","metaDescription":"SN75976A1MDGGREP half-duplex transceiver, 9/9 drivers/receivers, -55°C to 125°C, 4.75V-5.25V supply.

The die and package are identical; the suffix indicates the reel packaging format. Functionally they are interchangeable, but confirm the reel quantity and tape dimensions match your assembly line."},{"question":"Does SN75976A1MDGGREP require external termination resistors?","answer":"For RS-485 and RS-422 networks, termination resistors are typically required at the ends of the bus to match the characteristic impedance and prevent reflections. The transceiver itself does not include internal termination — the datasheet provides recommended resistor values based on cable length and data rate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN75976A1MDGGREP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN75976A1MDGGREP when reusing this data.
