Advance Information
EIA–232–E and CCITT V.28
The MC145407 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 MC145407 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
MC145407, since the MC145407 charge pumps have been designed to
guarantee
±
5 V at the output of up to six drivers. Thus, the MC145407 provides
a high–performance, low–power, stand–alone solution or, with the MC145406,
a + 5 V only, high–performance two–chip solution.
