Introduction

SN65HVD1176DRG4 is an integrated chip designed to provide up to two-channel low voltage bus transceiver service by Texas Instruments Inc. Together with two other chips, the SN65HVD1278DR and SP3889R, it forms the Amplicon trio series of open-collector receivers, transmitters, and transceivers. These parts are used for multiple uses such as low-voltage point-to-point communications and low-voltage serial data protocols. The SN65HVD1176DRG4 is specifically designed and manufactured for receptiveness to CAN (Controller Area Network) and other low-voltage differential and single-ended signal protocols. As part of the Amplicon series of transceivers, it is capable of communication by both connecting to two lines or four lines of logic signal paths. This article will discuss the application field, working principle, and features of the SN65HVD1176DRG4.

Application Field

The SN65HVD1176DRG4 chip is ideally suited for applications requiring an interface with low signal levels, such as automotive systems, industrial control systems, and office automation. These products are particularly useful for the reception and transmission of data in the 0 to 32 Volt DC range. It is ideal for changing logic states from high to low and other low-voltage operations such as low-voltage differential signal (LVDS) lines, fiber-optics and microwave links. The SN65HVD1176DRG4 can be used in applications such as clutch pedal position sensor, lighting control, engine diagnosis, or vibration control.

Working Principle

The SN65HVD1176DRG4 is an open-drain transceiver with two low voltage, active-low input/output ports. A single logic source pin is provided for a bidirectional control mode, or separate logic source pins can be used for the two ports in a half-duplex mode. When operating in half-duplex mode, the B port is not dependent on the A port. In other words, both ports can be configured independently.The SN65HVD1176DRG4 provides a TTL threshold switch capable of arbitrarily connecting other logic gates to either port, allowing for full device control at the logic level. This enables users to use the device for a variety of operations such as noise protection, low power operations, and power saving by enabling the connection between DC and AC components.When in active mode, the device allows for the connection between DC and LVDS components, as well as signals from 0V to 32V. The device has a simple translation circuit that couples TTL rounds to LVDS levels, allowing for bidirectional data communication.

Features

The SN65HVD1176DRG4 is designed to comply with various automotive standards, such as the AEC Q100-003, ISO 16750-2, and SAEJ1587 standards. It is also very reliable, as it provides voltage protection, ESD (electrostatic discharge) and latch-up protection.The SN65HVD1176DRG4 is designed to provide high noise immunity, wide common-mode range ( from -7V to 32V), high ripple rejection (up to 1MHz), and low propagation delay time of around 165nS for both LVDS and TTL levels. The power consumption of the SN65HVD1176DRG4 is very low, requiring only 140uA for both Enable and Disable modes.Other features include a low propagation delay and a low distortion signal of up to -5dB, allowing for high speed operations. Maximum package power rating is 1.5W and output switching speed of 20ns, with loading of 250pF. The SN65HVD1176DRG4 chip is also designed to be compatible with various logic levels, such as 3.3V, 5V, and 15V, and can withstand temperatures up to +125°C.

Conclusion

Overall, the SN65HVD1176DRG4 is an integrated IC designed to provide two-channel low voltage bus transceiver service. Packed with powerful features, such as low power consumption, high noise immunity, wide common-mode range, and low distortion signals, the SN65HVD1176DRG4 is an ideal choice for any low voltage point-to-point communication and low voltage serial data protocols. It is also very reliable and meets various automotive standards, making it a versatile chip for various applications.
