GD75232PWRE4

Overview

The GD75232PWRE4 is a low-power RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex data communication. It integrates three drivers and five receivers within a single package, supporting data rates up to 120 kb/s. The device operates on a single 5 V supply voltage with a maximum rating of 5.5 V and a minimum of 4.5 V. It features a typical operating supply current of 30 mA and functions reliably within an ambient temperature range of 0°C to +70°C. The component is housed in a 20-TSSOP surface-mount package and complies with RoHS standards.

Feature Summary

• Integrates three independent drivers and five receivers for complex serial interface requirements
• Supports full-duplex communication with standard RS-232 signal levels
• Operates from a single 5 V power supply with low quiescent current consumption
• Compatible with EIA/TIA-232-F and ITU-T V.28 standards

Applications

• Industrial control systems requiring multiple serial ports
• Modem interfaces and communication equipment
• Portable battery-operated instruments
• RS-232 compliant data transmission links

Procurement Notes

Verify the complete part number including the suffix 'E4' to ensure lead-free compliance and specific packaging configuration. Confirm the 20-TSSOP package variant matches the design footprint. Check manufacturer documentation for moisture sensitivity level and recommended soldering profiles to prevent assembly defects during reflow processes.

Selection Notes

Select this component when a single IC must handle multiple transmit and receive lines simultaneously. The 3-driver and 5-receiver configuration reduces board space compared to using separate dual transceivers. Ensure the application environment stays within the specified 0°C to +70°C operating temperature range for optimal performance and reliability.

Part Context

This part belongs to the GD75232 series of RS-232 transceivers from Texas Instruments. It shares core electrical specifications with variants like the GD75232DWR but differs in package type. The 'E4' suffix indicates lead-free construction and environmental compliance, distinguishing it from older non-compliant versions within the same functional family.

Replacement Considerations

Direct pin-compatible substitutes include other GD75232 variants such as GD75232PWR or GD75232DR, provided the package style matches the PCB layout. Verify that alternative components maintain the same 3-driver/5-receiver configuration and 120 kb/s data rate capability.
