MAX3243ECRHBR Description

Short technical summary and product information.

The Texas Instruments MAX3243ECRHBR is a versatile RS-232 transceiver designed for single-supply operation from 3V to 5.5V. This device integrates 3 drivers and 5 receivers, making it suitable for various serial communication applications.

 

Key electrical characteristics include a maximum data rate of 500kbps and robust ESD protection, with ±15kV Human-Body Model (HBM) and ±15kV IEC 61000-4-2 air-gap discharge protection. The transceiver operates over a wide temperature range of -40°C to 85°C.

 

Packaged in a 32-VQFN (5x5 mm) with a surface mount type, the MAX3243ECRHBR offers a compact solution for space-constrained designs. It features an auto-powerdown function to conserve energy when no valid RS-232 signal is detected and accepts 5V logic input with a 3.3V supply.

 

This transceiver meets or exceeds TIA/EIA-232-F and ITU V.28 standards, providing reliable communication for interfaces such as IBM PC/AT serial ports. Its design facilitates interchangeability with Maxim's MAX3243E.
