Fault Tolerant Low Speed CAN Transceiver
Dynamic Characteristics
The devices R1, C1 and C2 which values are given in the column "Condition" of the table below refer to
the test-schematic schown in Figure 4, ”Test Circuit for Dynamic Characteristics”
For the definition of propagation delay and transitions times see Figure. 2 - TH8053 Timing Diagram
