Bus-Pin Fault Protection Exceeds 36 V
The SN65HVD233, SN65HVD234, and SN65HVD235
are used in applications employing the controller area
network (CAN) serial communication physical layer in
accordance with the ISO 11898 standard. As a CAN
transceiver, each provides transmit and receive capability
between the differential CAN bus and a CAN controller,
with signaling rates up to 1 Mbps.
Bus-Pin ESD Protection Exceeds 16-kV HBM
GIFT/ICT Compliant (SN65HVD234)
Compatible With ISO 11898
(1)
Signaling Rates up to 1 Mbps
Extended –7-V to 12-V Common-Mode Range
High-Input Impedance Allows for 120 Nodes
LVTTL I/Os Are 5-V Tolerant
Designed for operation in especially harsh environments,
the devices feature cross-wire, overvoltage and loss of
ground protection to 36 V, with overtemperature
protection and common-mode transient protection of
100 V. These devices operate over a –7-V to 12-V
common-mode range with a maximum of 60 nodes on a
Adjustable Driver Transition Times for
Improved Signal Quality
