MC145583 Overview
This transceiver is a high performance, low power consumption device that is equipped with a standby function. A voltage tripler and inverter converts the + 3.3 V to ± 8.8 V, or a voltage doubler and inverter converts the + 5.0 V to ± 8.8 V. This is acplished through an on chip 40 kHz oscillator and five inexpensive external capacitors.
