MC145583 - 3.3 Volt Only Driver/Receiver with an Integrated Standby Mode

General Description

VCC Digital Power Supply (Pin 27) This digital supply pin is connected to the logic power supply.

This pin should have a not less than 0.33 µF capacitor GND.

232 E connector (Pin 7) as we

Key Features

  • rter, which generate the VDD and VSS voltages. Rx1, Rx2, Rx3, Rx4, Rx5 Receive Data Inputs (Pins 7, 8, 9, 11, 13) These are the EIA.
  • 232.
  • E receive signal inputs. A voltage between + 3 and + 25 V is decoded as a space, and causes the corresponding DO pin to swing to GND (0 V). A voltage between.
  • 3 and.
  • 25 V is decoded as a mark, and causes the DO pin to swing up to VCC. DO1, DO2, DO3, DO4, DO5 Data Outputs (Pins 22, 21, 20, 18, 16) These are the receiver digital o.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145583/D MC145583 Product Preview 3.3 Volt Only Driver/Receiver with an Integrated Standby Mode 28 1 DW SUFFIX SOG PACKAGE CASE 751F 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.
