Overview
The MAX3225EAP is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for full-duplex communication. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 1 Mbps. The device integrates two drivers and two receivers in a single package. Key electrical characteristics include a typical driver output voltage of ±6 V and receiver input thresholds compatible with standard RS-232 levels. The component is housed in a 20-pin SSOP package and is rated for an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates two independent drivers and two receivers for full-duplex RS-232 communication
- Operates on a single 3.0 V to 5.5 V power supply using external charge pumps
- Supports data transmission rates up to 1 Mbps
- Includes ESD protection on all RS-232 lines
Applications
- Industrial control systems requiring serial communication
- Portable instrumentation and medical devices
- Modem and fax machine interfaces
- Point-of-sale (POS) terminals
Procurement Notes
Verify the specific suffix 'EAP' against the manufacturer's current datasheet to confirm the package type and temperature grade. Ensure compatibility with existing PCB footprints for the 20-pin SSOP configuration. Check for RoHS compliance status if required by regional regulations. Confirm availability through authorized distributors as stock levels vary.
Selection Notes
Select this component when a dual-channel RS-232 interface is needed with low power consumption. It is suitable for applications requiring operation from a single 3V or 5V supply. Compare with the MAX3223EAP if lower data rates are sufficient, or the MAX3225ECUP+ for alternative packaging options. Ensure the design accommodates the necessary external capacitors for the internal charge pump circuitry.
Part Context
This part belongs to the Maxim MAX322x family of low-power RS-232 transceivers. These devices are widely used in embedded systems where space and power efficiency are critical constraints. The MAX3225 variant specifically provides two channels, distinguishing it from single-channel models like the MAX3222 or higher-density variants in the same series.
