Product Summary

The MC145407P is a silicon–gate CMOS IC that combines three drivers and three receivers to fulfill the electrical specifications of EIA–232–E and CCITT V.28 while operating from a single + 5 V power supply. 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 three drivers and three receivers of the MC145407P are virtually identical to those of the MC145406. Therefore, for applications requiring more than three drivers and/or three receivers, an MC145406 can be powered from an MC145407P, since the MC145407P charge pumps have been designed to guarantee ± 5 V at the output of up to six drivers. Thus, the MC145407P provides a high–performance, low–power, stand–alone solution or, with the device, a + 5 V only, high–performance two–chip solution.
