Key Features
- 3-driver RS-232 transceiver with Schmitt-trigger inputs improves noise immunity on long serial communication lines
- Wide 4.5 V to 15 V supply range accommodates both legacy 12 V RS-232 systems and lower-voltage designs
- EIA-232-F / TIA-232-F / V.28 compliant for direct interface to UART and IBM PC/AT-style serial port connectors
Applications
The GD75232DWE4 is designed for legacy serial communication interfaces in industrial equipment, embedded systems, and PC peripheral connections that require EIA-232-F compliant signal levels. Its Schmitt-trigger inputs and multi-driver configuration make it suitable for noisy factory floor environments where RS-232 cables may exceed 3 meters.

Frequently Asked Questions
How does the Schmitt-trigger input of the GD75232DWE4 improve signal integrity on long RS-232 cable runs?
Schmitt-trigger inputs add hysteresis of typically 0.5 V to the switching threshold, preventing multiple false transitions when the received RS-232 signal has slow edges or superimposed noise. This is especially valuable on cable runs exceeding 3 meters at 9600 baud, where capacitive loading can degrade edge rates to below the EIA-232-F minimum slew rate of 30 V/µs.
What supply voltage range does the GD75232DWE4 require, and how does that affect compatibility with modern 3.3 V microcontroller boards?
The GD75232DWE4 operates from a 4.5 V to 15 V supply and requires a separate charge-pump or external ±12 V supply to generate RS-232-compliant output swing levels of ±5 V to ±15 V. When interfacing with a 3.3 V microcontroller, a level-shifting stage or a single-supply RS-232 transceiver with an integrated charge pump should be considered to avoid over-voltage on the logic-side inputs.
For a 3-wire RS-232 link between a microcontroller UART and a PC serial port, how does the GD75232DWE4 simplify the interface?
The GD75232DWE4 provides 3 drivers directly configurable for TX, RTS, and DTR lines, plus 4 receivers for RX, CTS, DSR, and DCD signals, covering a full handshaking RS-232 interface in a single 20-pin SOIC package. This eliminates the need for discrete level-shift components and matches the signal-count requirements of IBM PC/AT DB-9 serial port connectors operating at data rates up to 115.2 kbps.
