1 / 7 page www.lansdale.com ML145583 3.3 Volt Only Driver/Receiver with an Integrated Standby Mode RS 232/EIA–232–E and CCITT V.28 Page 1 of 7 Issue A Legacy Device: Motorola MC145583 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. FEATURES Drivers: • ± 5 V Minimum Output Swing at 3.3 or 5.0 V Power Supply • 300 Ω Power–Off Impedance • Output Current Limiting • Three–State Outputs During Standby Mode Receivers: • ± 25 V Input Range • 3 to 7 k Ω Input Impedance • 0.8 V Hysteresis for Enhanced Noise Immunity • Three–State Outputs During Standby Mode Ring Monitor Circuit: • Invert the Input Level on Rx1 to Logic Output Level on RIMON at Standby Mode 28 1 SOIC 28W = -7P SOG PACKAGE CASE 751F MOTOROLA SOIC 28W MC145583DW ML145583-7P LANSDALE PACKAGE Note: Lansdale lead free (Pb) product, as it becomes available, will be identified by a part number prefix change from ML to MLE.
