概述
Description
The MAX213IDBR is a RS-232 transceiver from Maxim Integrated (now part of Analog Devices). It features four drivers and five receivers, supporting data rates up to 120kbps. Designed for low-power operation, it includes a shutdown mode to reduce power consumption.
Key features:
- ±15kV ESD protection (on RS-232 I/O lines)
- 3.0V to 5.5V supply range
- Auto-powerdown for energy efficiency
- TIA/EIA-232-F compliant
Packaged in a SSOP-28 (DBR) form factor, it’s ideal for portable devices, industrial systems, and embedded applications requiring robust serial communication.
For detailed specs, refer to the datasheet.
