EIA–232–E and CCITT V.28
The MC145705/06/07 are a series of silicon–gate CMOS transceiver ICs that
fulfill the electrical specifications of EIA–232–E and CCITT V.28 while operating
from a single + 5 V power supply. 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.
