MAX3389E
MAX3389E is ESD-Protected RS-232Transceivers manufactured by Maxim Integrated.
- Part of the MAX3388E comparator family.
- Part of the MAX3388E comparator family.
Description
The MAX3388E/MAX3389E are 2.5V-powered EIA/TIA232 and V.28/V.24 munications interfaces with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection. The MAX3388E/MAX3389E have two receivers and three transmitters. All RS-232 inputs and outputs are protected to ±15k V using the IEC 1000-4-2 Air-Gap Discharge method, ±8k V using the IEC 1000-4-2 Contact Discharge method, and ±15k V using the Human Body Model.
In addition to the traditional RS-232 I/O, these devices have dedicated logic-level I/O pins for additional device-todevice handshaking. During shutdown the logic-level I/O pins are active for the MAX3389E. An internal 62Ω switch is provided to switch power to external circuitry or modules.
A proprietary low-dropout transmitter output stage enables RS-232 patible performance from a +2.35V to...
