3 RS-232 Transceiver Key Specification Overview

When planning an RS-232 based communication system, there are many different transceiver options to choose from. To be able to quickly navigate to parts that are designed for a specific use case or application there are a few key specifications along with some optional features that are common to RS-232 compliant devices. These areas of interest can be broken down into three categories: electrical characteristics, timing and switching characteristics, and optional features that can be present in RS-232 compliant devices.
