1 / 8 page MC145583 MOTOROLA 1 Product Preview 3.3 Volt Only Driver/Receiver with an Integrated Standby Mode EIA–232–E and CCITT V.28 The MC145583 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 consumption device that is equipped with a standby function. A voltage tripler and inverter converts the + 3.3 V to ± 8.8 V, or a voltage doubler and inverter converts the + 5.0 V to ± 8.8 V. This is accomplished through an on–chip 40 kHz oscillator and five inexpensive external capacitors. 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 kΩ 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 This document contains information on a product under development. Motorola reserves the right to change or discontinue this product without notice.
