The SN65HVD1786D from Texas Instruments is a popular differential bus transceiver that can be used in various applications. It features a high-voltage operational amplifier and hysteretic comparator, making it ideal for open- and short-detect applications in systems that require a high-speed, fault-tolerant protocol. The device is also suitable for many other applications, including line-driver and receiver tasks, as well as redundant power-line communications.
The SN65HVD1786D is a differential bus transceiver that is used to provide high-speed data communication. The device supports up to a 5 Mbps data rate, with a wide common-mode voltage range of -7 V to +12 V. The transceiver has a 16-bit data input, four control/status bits and a separate flag bit.The SN65HVD1786D is designed to allow two transceivers, usually on different buses, to communicate with each other over a single pair of wires. The device supports full-duplex operation with balanced signal pairs. The transceiver is capable of driving both sides of the signal, allowing for higher compatibility with varying transmission lines.The SN65HVD1786D has an advanced feature set that includes: both open-detect and short-detect capabilities, active power-up and power-down signals, a 400 ns minimum flag time, and three levels of protection from electrostatic discharge (ESD).
The SN65HVD1786D is ideal for applications in which a fault-tolerant, high-speed protocol is required, such as industrial bus networks, fieldbus systems, factory automation, or process control. Other applications include line-driver and receiver tasks, redundant power-line communications, and medical imaging.
The SN65HVD1786D is based on a current-mode logic (CML) architecture. It is designed to interface directly with digital logic systems without the need for external components. The device is configured by a 3-bit mode select input that enables several predefined working modes, depending on the application.In normal operation, both the transmit and receive channels are enabled. The transmitter is enabled by applying a logic high signal at the “Transmit Enable” pin, while the receiver is enabled by applying a logic low signal at the “Receive Enable” pin. The transmitter section consists of a current source and dynamic resistor, while the receiver includes an active hysteretic comparator with a fixed gain.The SN65HVD1786D features differential output drivers that are capable of driving a wide range of loads. The outputs can swing as low as 0.1 V and as high as 5 V, with a typical propagation delay of 4 ns. The devices low-voltage design prevents excessive power dissipation during active-high operation, resulting in fast switching speeds and overall improved system performance.
In summary, the SN65HVD1786D is a high-speed differential bus transceiver from Texas Instruments that is used in various applications. It features a hysteretic comparator and operational amplifier, making it ideal for open- and short-detect applications. The device is also suitable for other tasks, such as line-driver and receiver tasks, as well as redundant power-line communications. Its low-voltage design and wide range of load capacitances make it a popular choice for fault-tolerant, high-speed protocols, industrial bus networks, and factory automation applications.
