MC33390 : Pin 1 2 3 Pin Name SLEEP GND LOAD BUS VBAT 4X/LOOP Tx Rx Description 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. Freescale Semiconductor, Inc... 4 5 .
