Philips Semiconductors
Fault-tolerant CAN transceiver
Preliminary specification
TJA1053
CHARACTERISTICS
VCC = 4.75 to 5.25 V; VSTB = VCC; VBAT = 6 to 27 V; Tamb = −40 to +125 °C; unless otherwise specified. All voltages are
defined with respect to ground. Positive currents flow into the IC. All parameters are guaranteed over the temperature
range by design, but only 100% tested at 25 °C.
