6 Specifications

6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT
VCC Supply voltage –0.3 6 V
Voltage range at bus terminals (CANH, CANL, SPLIT) –27 40 V
IO Receiver output current 20 mA
VI Voltage input, ISO 7637 transient pulse(2) (CANH, CANL) –150 100 V
VI Voltage input (TXD, STB) –0.3 6 V
TJ Junction temperature –40 150 °C
Tstg Storage temperature –40 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Tested in accordance with ISO 7637 test pulses 1, 2, 3a, 3b per IBEE system level test (Pulse 1 = –100 V, Pulse 2 = 100 V, Pulse 3a = –150 V, Pulse 3b = 100 V). If DC may be coupled with ac transients, externally protect the bus pins within the absolute maximum voltage range at any bus terminal. This device has been tested with dc bus shorts to 40 V with leading common-mode chokes. If common-mode chokes are used in the system and the bus lines may be shorted to DC, ensure that the choke type and value in combination with the node termination and shorting voltage either will not create inductive flyback outside of voltage maximum specification or use an external transient-suppression circuit to protect the transceiver from the inductive transients.

tPHL Propagation delay time, high-to-low level output STB at 0 V, See Figure 5 25 45 120 ns
tr Differential output signal rise time STB at 0 V, See Figure 5 25 ns
tf Differential output signal fall time STB at 0 V, See Figure 5 45 ns
ten Enable time from standby mode to normal mode and transmission of dominant See Figure 8 10 µs
t(dom) Dominant time-out(1) ↓VI, See Figure 11 300 450 700 µs
RECEIVER SWITCHING CHARACTERISTICS
tPLH Propagation delay time, low-to-high-level output STB at 0 V , See Figure 7 60 90 130 ns
tPHL Propagation delay time, high-to-low-level output STB at 0 V , See Figure 7 45 70 130 ns
tr Output signal rise time STB at 0 V , See Figure 7 8 ns
tf Output signal fall time STB at 0 V , See Figure 7 8 ns
tBUS Dominant time required on bus for wakeup from standby STB at VCC, See Figure 13 1.5 5 µs
(1) The TXD dominant time-out (t(dom)) disables the driver of the transceiver once the TXD has been dominant longer than t(dom), 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 5 successive dominant bits are followed immediately by an error frame. This, along with the t(dom) minimum, limits the minimum bit rate. The minimum bit rate may be calculated by:
Minimum Bit Rate = 11/ t(dom) = 11 bits / 300 µs = 37 kbps
