Enables the transceiver when Logic 1 and disables the transceiver when Logic 0.
Device ground pin.
Accommodates an external pull-down resistor to ground to provide loss of ground protection.
Waveshaped SAE Standard J-1850 Class B transmitter output and receiver input.
Provides device operating input power.
Tristate input mode control; Logic 0 = normal waveshaping, Logic 1 = waveshaping disabled for 4X
transmitting, high impedance = loopback mode.
Serial data input (DI) from the microcontroller to be transmitted onto Bus.
Bus received serial data output (DO) sent to the microcontroller.
