SBOA442 March 2021 TMP107 , TMP107-Q1
Figure 4-1 shows the implementation with the RS-485 transceiver. The transceiver features complementary enable signals for the transmitter and the receiver. This integrated functionality replaces the SN74LVC2G241 buffer from the CAN-based circuit. For this reason, the DIR signal from the TLC555-Q1 timer connects directly to the DE and ~RE signals.
