GD75323DWR

Overview

The GD75323DWR is a Texas Instruments RS-232 transceiver housed in a 20-SOIC surface-mount package. It integrates five drivers and three receivers for full-duplex communication with a data rate of 120 kb/s. The device operates on a single 5 V supply, ranging from 4.5 V to 5.5 V, with typical quiescent currents of 20 mA and 32 mA. It supports an operating temperature range of 0°C to +70°C and includes a 500 mV receiver hysteresis.

Feature Summary

• Integrates multiple independent drivers and receivers within a single IC
• Supports full-duplex data transmission over standard RS-232 protocols
• Designed for operation with a single low-voltage power supply

Applications

• Industrial control systems requiring serial communication
• Modem interfacing applications
• Point-to-point or multi-drop communication links

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements before integration into the manufacturing process. Ensure the component matches the exact pinout and electrical characteristics defined in the manufacturer datasheet.

Selection Notes

Select this component when a design requires five transmit channels and three receive channels. Verify that the 120 kb/s speed meets system timing requirements. Ensure the SOIC-20 footprint aligns with the PCB layout constraints and that the 5 V logic levels are compatible with the connected microcontroller or processor.

Part Context

This part belongs to the GD75323 series of RS-232 interface integrated circuits manufactured by Texas Instruments. It serves as a line transceiver designed to convert TTL/CMOS logic levels to RS-232 voltage levels for reliable serial data exchange in electronic equipment.
