DC electrical characteristics

The following tables provide DC characteristics for bidirectional pads:

•

Table 20 provides output driver characteristics FlexRay I/Os (SYM).

•

Table 21 provides output driver characteristics for LFAST I/Os.

NOTE

Fast IOs must be specified only as fast (and not as high current). See

Table 22.

Table 20. FlexRay (SYM) configuration output buffer electrical characteristics1
