The TRS3243EIPWR from Texas Instruments is a versatile RS-232 transceiver IC that operates from a single 3V to 5.5V supply. It integrates three line drivers and five line receivers, making it suitable for standard serial port applications.
This device supports data rates up to 500kbps and meets or exceeds TIA/EIA-232-F and ITU v.28 standards. A key feature is its robust ESD protection, offering ±15kV on RS-232 bus pins via Human-Body Model (HBM) and IEC61000-4-2 (Air-gap discharge), and ±8kV via IEC61000-4-2 (Contact discharge).
Designed for ease of use, the TRS3243EIPWR includes a dual charge-pump circuit and requires only four small external capacitors. It also features low standby current (1µA typical) and an auto-powerdown function to conserve energy when no valid RS-232 signal is detected. The device is available in a 28-TSSOP package and operates within a temperature range of -40°C to 85°C.
Its design makes it interchangeable with industry-standard '3243E devices and suitable for applications requiring a single-supply interface for serial communication, such as in IBM PC/AT compatible systems.
