Philips Semiconductors
Preliminary specification
High speed CAN transceiver
TJA1050
CHARACTERISTICS
VCC = 4.75 to 5.25 V; Tamb = −40 to +125 °C; RL = 60 Ω unless specified otherwise; all voltages are referenced to GND
(pin 2); positive currents flow into the IC; all parameters are guaranteed over the ambient temperature range by design,
but only 100% tested at Tamb = 25 °C unless specified otherwise.
