Product Overview
The SN65HVD233 is a Texas Instruments 3.3-V CAN bus transceiver for Signal_Chain designs requiring ISO 11898-2 compatible physical-layer communication. It operates from a single 3.3 V supply, with a recommended VCC range of 3 V to 3.6 V, and supports CAN serial communication rates up to 1 Mbps.
The CANH and CANL interface supports a recommended bus terminal and common-mode range of -7 V to 12 V, with absolute maximum CANH or CANL terminal ratings from -36 V to 36 V. The bus pins also include HBM ESD ratings exceeding +/-16 kV for CANH, CANL, and GND, while all pins are rated to 3000 V HBM and +/-1000 V CDM.
Control and logic interfacing use 5 V tolerant LVTTL I/O. High-level input voltage is specified from 2 V to 5.5 V, and low-level input voltage from 0 V to 0.8 V for D, EN, AB, and LBK inputs. The RS pin supports slope-control selection with 0 kOhm to 100 kOhm resistance to ground, including about 15 V/us with 10 kOhm and about 2.0 V/us with 100 kOhm.
The device is supplied in an SOIC (8), 4.90 mm x 3.91 mm nominal body package. Operating free-air temperature is specified from -40 degC to 125 degC for SN65HVD233, SN65HVD234, and SN65HVD235.

Procurement Notes
When requesting a quote for SN65HVD233, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
