TRS202CDG4

Drivers, Receivers, Transceivers Overview

The TRS202CDG4 is a dual RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 5-V supply voltage with a range of 4.5 V to 5.5 V. The device provides two drivers and two receivers, supporting full-duplex communication at data rates up to 120 kbit/s. It features ±15-kV electrostatic discharge (ESD) protection on the RS-232 bus pins according to the Human-Body Model. The internal charge pump requires four external 0.1-µF capacitors for operation. The component is housed in a 16-pin SOIC package and supports an operating temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated dual charge-pump circuit enables operation from a single 5-V power supply without requiring additional voltage rails.
• Built-in advanced ESD protection structures safeguard RS-232 bus pins against ±15-kV human-body model discharges while powered down.
• Meets or exceeds TIA/EIA-232-F and ITU v.28 standards for asynchronous serial communication interfaces.

Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix G4 indicates lead-free packaging compliant with RoHS directives. Confirm the specific package variant matches the required PCB footprint. Ensure the temperature grade aligns with the intended operational environment. Cross-reference the active status with current manufacturer documentation before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing serial port interfaces requiring robust ESD protection for handheld devices. Verify that the system can accommodate the four required 0.1-µF external capacitors for the charge pump. Ensure the 120 kbit/s maximum data rate satisfies the application's throughput requirements. Check thermal dissipation limits if operating near the upper temperature boundary.

Drivers, Receivers, Transceivers Part Context
