• Manufacturer Part Number: ncv7425a
• Description: Ncv7425 Lin Transceiver With Voltage Regulator And Reset Pin
• Manufacturer: ON Semiconductor

18. The AC parameters are specified for following RC loads on the LIN bus: L1 = 1 kW / 1 nF; L2 = 660 W / 6.8 nF; L3 = 500 W / 10 nF.
19. Low slope mode is not compliant to the LIN 1.3 or LIN 2.0/2.1 standard.
