LTC2803CGN-1#PBF

Drivers, Receivers, Transceivers Overview

The LTC2803CGN-1#PBF is a dual RS-232 transceiver in a 16-lead narrow SSOP package. It operates on a single supply voltage ranging from 1.8V to 5.5V and includes an integrated DC-to-DC converter to generate the necessary positive and negative voltages for RS-232 signaling. The device supports data rates up to 250kbps with a 1nF load and 100kbps with a standard 2.5nF load. It features low-power modes, including a shutdown mode drawing 1µA and a receivers-active mode drawing 15µA. The component complies with TIA/EIA-232-F standards and offers protection against ±10kV ESD.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix and temperature grade when sourcing replacements. Confirm that the replacement component matches the original pinout and electrical specifications. Check for availability of the narrow SSOP-16 package type. Ensure compliance with RoHS directives if required by the design specification.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring dual RS-232 channels with low power consumption. It is suitable for applications powered by two alkaline or NiMH cells due to the wide input voltage range. Consider the 250kbps maximum data rate when designing for high-speed serial communication requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2801 family of single and dual RS-232 transceivers. The CGN-1 designation indicates the commercial temperature range (0°C to 70°C) and the narrow SSOP-16 package. Other variants in the series include the LTC2801, LTC2802, and LTC2804, which offer different channel counts or higher speed capabilities.
