Overview
The SN65C3232EDRG4, produced by Texas Instruments, is a dual transmitter/receiver RS-232 interface IC. This component is part of the interface and bus line transceivers category and is designed to provide the electrical interface between an asynchronous communication controller and a serial-port connector.
Introduced on January 1, 1995, this device is compliant with industry standards such as TIA/EIA-232-F and features robust ESD protection. It operates with a single 3-V to 5.5-V supply and includes a dual charge-pump circuit that requires four small external capacitors for operation.
