SN75C3222DBRE4

Introduction

The SN75C3222DBRE4 is a two-channel integrated cir­cuit in the SN75C family. It features an iso­lated driver and receiver path that provides high-current capability and high speed interfaces for com­plete isolation of power and data signals. The SN75C3222DBRE4 driver and receiver are designed for fieldbuses such as Profibus, CAN and CANopen and is ideal for embedded applications.

Application Field

The SN75C3222DBRE4 is applicable for use in a va­riety of applications. It can be used in profes­sional embedded systems as an Ethernet interface, as well as in complex communication protocols such as AL, PROFIBUS and CAN. Additionally, it can be used as an audio interface in multi-room audio systems.

The SN75C3222DBRE4 is suitable for industrial and medical automation applications, such as the man­agement of process controls, robotics, and smart grids. Furthermore, it can be used in monitor­ing and security applications, as well as in consumer electronics applications such as robots, remote controls, and home automation systems.

Work Principle

The SN75C3222DBRE4 operates on a standard logic-level voltage and typical operating frequencies range from 10kHz up to 1MHz. The logic level design features two complete input and output paths that provide an isolated data interface. The SN75C3222DBRE4 has TTL-compatible logic levels and provides high-current driver capability of up to 50mA. The driver outputs can be driven to either a high or low state and the inputs provide a logic-level data output. The receiver outputs can also be driven to either high or low state, giving the user control over the data interface.

The SN75C3222DBRE4 features low propagation and high output slew rates. The propagation delay is typically 1ns and the output slew rate is typically 32ns. These features provide a high speed, low noise interface that is ideal for hi-speed communications systems.

Conclusion

The SN75C3222DBRE4 is a two-channel, isolated interface solution for industrial, medical and consumer electronic applications. It offers high-current capability, TTL-compatible logic levels and high speed operation up to 1 MHz. The SN75C3222DBRE4 is an ideal solution for applications requiring complete isolation of power and data signals.
