3.3 Volt Only Driver/Receiver with

an Integrated Standby Mode

RS 232/EIA–232–E and CCITT V.28

Legacy Device: Motorola MC145583

SOIC 28W = -7P

The ML145583 is a CMOS transceiver composed of three drivers and

five receivers that fulfills the electrical specifications of EIA–232–E,

EIA–562, and CCITT V.28 while operating from a single + 3.3 or + 5.0 V

power supply. This transceiver is a high–performance, low–power con-

sumption device that is equipped with a standby function.

A voltage tripler and inverter converts the + 3.3 V to 8.8 V, or a volt-

age doubler and inverter converts the + 5.0 V to 8.8 V. This is accom-

plished through an on–chip 40 kHz oscillator and five inexpensive exter-

nal capacitors.
