SN65HVD230D

Introduction

The SN65HVD230D is a low-power, high-speed, high-performance differential line transceiver designed for use in EIA-232 and V.24 communications and applications. It has been designed for use in applications where a 3.3V or 5V supply is available, such as PCMCIA cards, battery operated systems, embedded systems or any other system with limited power options. The SN65HVD230D is capable of transmitting and receiving data at speeds up to 250kbps on a 3.3V power supply, and up to 500kbps on a 5V power supply.

Application Field

The SN65HVD230D is ideal for applications where a robust, low-power, high-speed transceiver is needed. The device is well suited for industrial and consumer applications, including handheld electronics and data communication devices. It is also suitable for communications over long distances, and can be used in applications such as routers and modems. The SN65HVD230D can also be used in general-purpose communications and can be used in both point-to-point and point-to-multipoint applications, such as systems with multiple nodes communicating with a single master.

Working Principle

The SN65HVD230D(TI) is a differential line transceiver designed to be compatible with the RS-232, V.24 and other related standards. It contains two independent transceivers, with each side of the transceiver includes two fully differential line drivers and two differential line receivers. The transceivers are powered by a 3.3V or 5V power supply, and in normal operating mode use a single ground between them. Each transceiver is designed to support data transmission speeds up to 250kbps on a 3.3V power supply, and up to 500kbps on a 5V power supply.

For the transmit pair, the SN65HVD230D contains two fully differential line drivers. The signal outputs of the drivers provide a differential output level that is clamped to a selected common-mode range by external resistors, and this level is independent of the supply voltage. The receiving pair of the transceivers contains two differential line receivers, which can receive signals over long distances without significant noise and signal distortion due to the built-in common-mode rejection ratio (CMRR). The receivers are capable of responding to signals having their levels within a certain range, while they detect the signal and provide a logic-level output. The device also includes an enable pin, which allows the user to control the power consumption of the device.

Conclusion

The SN65HVD230D is a high-performance differential line transceiver, which provides excellent performance in both industrial and consumer applications. It can be used in applications such as routers, modems and other general-purpose communications, but is well suited for applications such as handheld electronics and data communication devices and can be used in both point-to-point and point-to-multipoint applications. The device is powered by either a 3.3V or 5V power supply, and is capable of transmitting and receiving data at speeds up to 250kbps on a 3.3V power supply, and up to 500kbps on a 5V power supply. The device also features an enable pin which allows the user to control the power consumption of the device.
