Definition

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.

TX

Serial data input (DI) from the microcontroller to be transmitted onto Bus.

8

RX

Bus received serial data output (DO) sent to the microcontroller.
