The SN65HVD230Q/231Q/232Q 3.3-V CAN transceivers provide the interface between the 3.3-V
TMS320Lx2403/6/7 CAN DSPs and the differential bus line, and are designed to transmit data at signaling rates
up to 1 Mbps as defined by the ISO 11898 standard.
features of the SN65HVD230Q, SN65HVD231Q, and SN65HVD232Q
The SN65HVD230Q/231Q/232Q are pin-compatible (but not functionally identical) with one another and,
depending upon the application, may be used with identical circuit boards.
These transceivers feature 3.3-V operation and standard compatibility with signaling rates up to 1 Mbps, and
also offer 16-kV HBM ESD protection on the bus pins, thermal shutdown protection, bus fault protection, and
open-circuit receiver failsafe. The failsafe design of the receiver assures a logic high at the receiver output if
the bus wires become open circuited. If a high ambient operating environment temperature or excessive output
current result in thermal shutdown, the bus pins become high impedance, while the D and R pins default to a
logic high.
