MAX13041 Datasheet, PDF (5/21 Pages) Maxim Integrated Products – ±80V Fault-Protected High-Speed CAN Transceiver with Low-Power Management and Wake-On CAN

±80V Fault-Protected High-Speed CAN Transceiver
with Low-Power Management and Wake-On CAN
TIMING CHARACTERISTICS
(V_CC = +4.75V to +5.25V, V_I/O = +2.8V to V_CC, V_BAT = +5V to +76V, T_A = T_MIN to T_MAX, R_L = 60Ω, unless otherwise noted. Typical
values are at V_CC = +5V, V_I/O = +3.3V, V_BAT = +12V and T_A = +25°C.) (Note 2)

Note 1: Positive current flows into the device.
Note 2: Limits over the operating temperature range are tested at worst-case supply voltage and compliant over the complete voltage
range.
Note 3: Current measured at +20V and guaranteed by design up to +40V.
Note 4: Common-mode voltage range ±40V.
Note 5: A remote wake-on CAN request is generated upon the detection of two dominant bus cycles, each followed by a recessive
bus cycle.
