MAX3243IDB Description

Short technical summary and product information.

The Texas Instruments MAX3243IDB is a multichannel RS-232 line driver and receiver designed for single-supply operation from 3V to 5.5V. This transceiver features three drivers and five receivers, meeting or exceeding TIA/EIA-232-F and ITU V.28 standards.

 

Key electrical specifications include a maximum data rate of 250kbps and ±15kV ESD protection using the Human-Body Model (HBM). The device operates within a temperature range of -40°C to 85°C. It consumes low active current (300µA typical) and standby current (1µA typical), with an auto-powerdown feature to conserve energy when no valid RS-232 signal is sensed.

 

Packaged in a 28-SSOP, the MAX3243IDB is suitable for surface mount applications. It accepts 5V logic input with a 3.3V supply and requires external capacitors for operation. The device is designed for single-chip, single-supply interface applications, including those for IBM PC/AT serial ports.
