1 Introduction

While both photorelays and analog switches can be used for similar functionality, their data sheets do vary widely, so knowing and understanding the specifications is crucial for making sure of compatibility when replacing a photorelay with an analog switch. Replacing photorelays with one of TI’s high-voltage analog switches can provide substantial improvements in system size, cost, and performance, especially in applications like automated test and measurement systems.
