概要
Description
LTC2861IDE is not a standalone IC; it’s the Analog Devices development/evaluation package for the LTC2861 isolated RS-485/RS-422 transceiver. The package typically includes an evaluation board (EVM), reference schematics/layouts, example circuits, and often a GUI or software to configure and test the device. It’s designed to help engineers quickly evaluate performance (bus timing, isolation/fault protection, biasing, MCU interfacing) and validate designs before committing them to a PCB. If you meant a different product or a specific software IDE, please share a link or exact term and I can tailor the info.

Pinout
- Pin count: 8 pins (8-pin package)
- Function: Single-channel isolated RS-485/RS-422 transceiver
- Typical pins: DI (driver input), RO (receiver output), DE (driver enable), RE (receiver enable), A/B (differential bus), VCC and GND (logic/bus supply). Note: isolation may involve separate supply/domain pins depending on package variant.

Manufacturer
Manufacturer: Analog Devices, Inc. (AD).
What kind of company: A global, U.S.-based semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing ICs. AD acquired Linear Technology (the original maker of LTC parts) in 2017, so LTC parts are now offered under the Analog Devices brand.
