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.
