LTC2804CGN-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2804CGN-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 an integrated DC-to-DC converter that generates the necessary positive and negative voltages for RS-232 signaling, eliminating the need for external charge pumps. The device supports data rates up to 1Mbps with a 250pF/3kΩ load and includes low-power modes, such as shutdown (1µA) and receivers-active (15µA). It is housed in a 16-lead narrow SSOP package and complies with TIA/EIA-232-F standards.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the CGN-1 designation corresponds to the commercial temperature grade and narrow SSOP package type required for your design. Ensure compatibility with your PCB footprint specifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring dual RS-232 channels with low power consumption. The CGN-1 variant is suitable for commercial temperature ranges. Consider the SSOP-16 package dimensions during layout. Verify that the system logic voltage aligns with the VL pin requirements for proper signal level translation.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2801 family of single and dual RS-232 transceivers. The LTC2804 specifically provides two drivers and two receivers. It shares architectural similarities with the LTC2801, LTC2802, and LTC2803 but differs in channel count and maximum data rate capabilities depending on the specific model within the series.
