If your microcontroller runs on 5V I/O, you need level translation or a different transceiver rated for 5V supply. The 120 mV hysteresis helps with signal integrity on noisy buses, but it doesn't change the supply requirement. ## SOT-23-8 package — board area and layout notes Housed in a SOT-23-8 package (Supplier Device Package: SOT-23-8), this transceiver occupies minimal PCB real estate — roughly 2.9 mm x 2.8 mm footprint. Surface-mount only, no exposed pad. The small package means the decoupling capacitor needs to sit close; a 100 nF ceramic within 2 mm of the VCC pin is the usual practice. No thermal vias required at the current draw of a CAN transceiver, but keep the CANH/CANL traces short to the connector and avoid stubs. The base product number is TCAN337, covering the family; this specific suffix (GDCNT) denotes the SOT-23-8 package and tape-and-reel / cut-tape delivery.","metaTitle":"TCAN337GDCNT CAN Transceiver, 5 Mbps, SOT-23-8","metaDescription":"Texas Instruments TCAN337GDCNT CAN transceiver with 5 Mbps data rate, 3V to 3.6V supply, 120 mV hysteresis, SOT-23-8, -40°C to 125°C.

The 3.3V supply is for the transceiver's own VCC and logic interface (TXD, RXD). If your CAN controller runs on 5V I/O, you need level translation between the controller and the transceiver's logic pins."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TCAN337GDCNT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TCAN337GDCNT when reusing this data.
