LTC2801IDE#PBF

Drivers, Receivers, Transceivers Overview

The LTC2801IDE#PBF is a single-driver, single-receiver 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 supplies for RS-232 signaling. The device supports data rates up to 250kbps with a 1nF/3kΩ load and 100kbps with a standard TIA/EIA-232-F load. It includes low-power modes, such as 1µA shutdown and 15µA receiver-active states. The component is housed in a 12-lead (4mm × 3mm) plastic DFN package and is rated for 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 for various logic families
• Low-power operation with distinct shutdown and receiver-active modes
• High ESD protection rating on RS-232 interface pins

Drivers, Receivers, Transceivers Applications

• Battery-powered systems requiring extended operational life
• Computers and consumer electronics with UART interfaces
• Diagnostic ports for industrial equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the temperature grade and packaging format. The 'I' designation indicates the industrial temperature range, while 'C' denotes commercial limits. Ensure the '#PBF' suffix corresponds to lead-free tape and reel or tube availability as required by the assembly process. Cross-reference the manufacturer's official documentation for current production status and compliance certifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel RS-232 interface is required within a narrow footprint constraint. The device is suitable for applications where the system logic voltage differs from the main power supply rail due to the separate VL pin. Consider the maximum data rate requirements against the load capacitance; higher speeds require lower capacitive loads. Evaluate the power budget to determine if the low-quiescent current modes provide sufficient battery life extension compared to standard transceivers.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2801/LTC2802/LTC2803/LTC2804 family of RS-232 transceivers. While sharing the same core architecture and power-saving features, other members of the series offer dual drivers/receivers or different package options like SSOP. The LTC2801 specifically provides the minimal configuration for single-ended communication needs.
