LTC2803IGN-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2803IGN-1#TRPBF is a dual RS-232 transceiver manufactured by Analog Devices Inc. It operates on a supply voltage range of 1.8V to 5.5V and features two drivers and two receivers. The maximum data rate is 250kbps for a 1nF/3kΩ load and 100kbps for a 2.5nF/3kΩ TIA/EIA-232-F load. The device includes an integrated DC-to-DC converter generating VDD and VEE supplies. Shutdown mode current is 1µA, while the receivers-active mode draws 15µA. It is housed in a narrow SSOP-16 package with an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter eliminates external charge pump components
• Logic supply pin enables independent level shifting from logic supply voltage
• Low-power modes include shutdown and receiver-active states for battery conservation
• Driver outputs are protected against short circuits and overload conditions

Drivers, Receivers, Transceivers Applications

• Battery-powered systems requiring extended operational life
• Computers and consumer electronics with serial communication needs
• Diagnostic ports for industrial equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing this component. Confirm that the IGN-1 designation corresponds to the industrial temperature grade required for your application environment. Ensure compatibility with existing PCB footprints for the narrow SSOP-16 package before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2803IGN-1#TRPBF when dual transceivers are necessary within a single channel footprint. This model supports half-duplex operation via low-latency output enable. Consider the 250kbps data rate limit when designing for high-speed serial interfaces. Verify that the system logic voltage aligns with the VL pin requirements for proper signal interfacing.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2801/LTC2802/LTC2803/LTC2804 family of RS-232 transceivers. It shares architectural similarities with the LTC2804 but differs in maximum data rate specifications. The part utilizes a switching regulator topology distinct from traditional charge-pump designs found in older RS-232 ICs.
