FlexRay transceiver

[1]

Current flows from VCC to VBUF. This means that the maximum sum current ICC + IBUF is 35 mA.

[2]

These values are based on measurements taken on several samples (less than 10 pieces). These measurements have taken place in

the laboratory and have been done at Tamb = 25 °C and Tamb = 125 °C. No characterization has been done for these parameters. No

industrial test will be performed on production products.

All parameters are guaranteed for VBAT = 6.5 V to 60 V; VCC = 4.75 V to 5.25 V; VBUF = 4.75 V to 5.25 V; VIO = 2.2 V to 5.25 V;

Tvj = −40 °C to +150 °C; Rbus = 45 Ω; RTRXD = 200 Ω unless otherwise specified. All voltages are defined with respect to

ground; positive currents flow into the IC.
