The single driver/receiver pair handles one CAN channel with a 120 mV receiver hysteresis that filters noise on the differential bus lines — enough margin to reject common-mode transients without losing valid recessive-to-dominant edges. AEC-Q100 qualification (Grade 0, -40°C to 150°C operating range) means this part is screened for the under-hood temperature band — an engine ECU or transmission controller that sees 125°C ambient still has 25°C of headroom before the die hits the abs-max junction limit. Hand-soldering is possible with a hot-air station and a fine tip, but the pad wicks heat quickly; a preheat plate helps avoid cold joints on the perimeter leads.","metaTitle":"NXP TJA1043TK/1Y CAN Transceiver, 5 Mbps, AEC-Q100, 14-HVSON","metaDescription":"NXP TJA1043TK/1Y automotive CAN transceiver, half-duplex, 5 Mbps data rate, AEC-Q100 qualified, -40 to 150°C, 14-HVSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Transceiver","Grade":"Automotive","Duplex":"Half","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"CANbus","Data Rate":"5Mbps","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Package / Case":"14-VDFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Receiver Hysteresis":"120 mV","Operating Temperature":"-40°C ~ 150°C","Supplier Device Package":"14-HVSON (3x4.5)","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.03","stockQuantity":23,"priceTiers":[{"qty":1,"price":"$2.03000","currency":"USD"},{"qty":10,"price":"$1.82200","currency":"USD"},{"qty":25,"price":"$1.71840","currency":"USD"},{"qty":100,"price":"$1.46420","currency":"USD"},{"qty":250,"price":"$1.37480","currency":"USD"},{"qty":500,"price":"$1.20296","currency":"USD"},{"qty":1000,"price":"$0.99674","currency":"USD"},{"qty":2500,"price":"$0.92800","currency":"USD"},{"qty":6000,"price":"$0.89363","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d41dba3e8f93f540e84c4fe8f603b2b4.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/TJA1043TK-1Y","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/TJA1043TK-1Y when reusing this data.
