What is the GD75232DWR?
The GD75232DWR is an RS-232 transceiver from Texas Instruments that integrates three drivers and five receivers into a single chip. It is designed to provide reliable communication between a UART interface and standard RS-232 serial ports.
What are the key features of the GD75232DWR?
This device supports data rates up to 120 kbit/s and meets the TIA/EIA-232-F and ITU V.28 standards. It also offers high ESD protection (HBM 1500V, CDM 500V, MM 200V), ensuring stable operation in environments where electrostatic discharge is a concern. Its 20-SOIC package and compatibility with SN75C185 and SN75185 pinouts make integration straightforward.
What is the GD75232DWR used for?
The GD75232DWR is commonly used in systems that require reliable RS-232 communication, such as industrial controllers, PC/AT-compatible equipment, embedded systems, point-of-sale terminals, and legacy serial-port interfaces. It serves as the interface between a UART and external RS-232 devices.
Why choose the GD75232DWR for my design?
Engineers choose this part because it offers robust electrical performance, strong ESD protection, compliance with established RS-232 standards, and straightforward compatibility with older TI transceivers—all of which help ensure dependable long-term operation.
Is it suitable for replacing older RS-232 transceivers?
Yes. Its pinout and functional compatibility with devices like the SN75C185 and SN75185 make it an excellent drop-in or near drop-in replacement in many existing designs.
