ML145407  
5 Volt Only Driver/Receiver  
RS232 EIA–232–E and CCITT V.28  
Legacy Device: Motorola MC145407  
The ML145407 is a silicon–gate CMOS IC that combines three  
drivers and three receivers to fulfill the electrical specifications of  
RS232 EIA–232–E and CCITT V.28 while operating from a single + 5  
V power supply. A voltage doubler and inverter convert the + 5V 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 ML145407 are virtually identical to those of  
the ML145406. Therefore, for applications requiring more than three  
drivers and/or three receivers, an ML145406 can be powered from an  
ML145407, since the ML145407 charge pumps have been designed to  
guarantee 5 V at the output of up to six drivers. Thus, the  
ML145407 provides a high–performance, low–power, stand–alone  
solution or, with the ML145406, a + 5 V only, high–performance  
two–chip solution.
