VCC = 5.5 V, VRXD = 5.5 V, TJ = 150°C, RL = 50 Ω, S at 0 V, Input to TXD at 500 kHz, 50% duty cycle square wave, CL_RXD = 15 pF.  Typical high load CAN operating conditions at 1mbps with 50% transmission (dominant) rate and loaded network. 268
THERMAL SHUTDOWN
Thermal shutdown temperature 170 °C
Thermal shutdown hysteresis 5 °C
(1) All typical values are at 25°C and supply voltages of VCC = 5 V and V(RXD) = 5 V, RL = 60 Ω.
(2) Loop delay symmetry for CAN with flexible data rate or "improved CAN" for data rates in excess of 1Mbps. Specified in accordance with working draft 2Mbps specification from physical layer task force within CAN in Automation.
(3) For the bus output voltage (recessive) will be the same if the device is in normal mode with S terminal LOW or if the device is in silent mode with the S terminal is HIGH.
(4) The TXD dominant timeout (t(TXD_DTO)) disables the driver of the transceiver once the TXD has been dominant longer than t(TXD_DTO), which releases the bus lines to recessive, preventing a local failure from locking the bus dominant. The driver may only transmit dominant again after TXD has been returned HIGH (recessive). While this protects the bus from local faults, locking the bus dominant, it limits the minimum data rate possible. The CAN protocol allows a maximum of eleven successive dominant bits (on TXD) for the worst case, where five successive dominant bits are followed immediately by an error frame. This, along with the t(TXD_DTO) minimum, limits the minimum bit rate. The minimum bit rate may be calculated by: Minimum Bit Rate = 11 / t(TXD_DTO) = 11 bits / 1175 µs = 9.4 kbps.
(5) The RXD timeout (t(RXD_DTO)) disables the driver of the transceiver once the RXD has been dominant longer than t(RXD_DTO), which releases the bus lines to recessive, preventing a local failure from locking the bus dominant. The driver may only transmit dominant again after RXD has been returned HIGH (recessive). While this protects the bus from local faults, locking the bus dominant, it limits the minimum data rate possible. The CAN protocol allows a maximum of eleven successive dominant bits (on RXD) for the worst case, where five successive dominant bits are followed immediately by an error frame. This, along with the t(RXD_DTO) minimum, limits the minimum bit rate. The minimum bit rate may be calculated by: Minimum Bit Rate = 11 / t(RXD_DTO) = 11 bits / 1380 µs = 8 kbps.
