These transceiver series are high performance and low power consumption devices that are equipped with standby and output enable function. A voltage doubler and inverter convert the + 5 V to ± 10 V. This is accomplished through an on–board 20 kHz oscillator and four inexpensive external electrolytic capacitors. The MC145705 is composed of two drivers and three receivers, the MC145706 has three drivers and two receivers, and the MC145707 has three drivers and three receivers. These drivers and receivers are virtually identical to those of the MC145407.
