Product Overview: SN75155D Dual Differential Line Receiver

The SN75155D from Texas Instruments is a versatile and robust integrated circuit designed for digital data transmission over long distances. This dual differential line receiver is part of the industry-standard 75155 series and is specifically engineered to convert balanced differential input signals to standard TTL (Transistor-Transistor Logic) output levels.

Key Features

• Dual Channels: The device contains two independent line receivers, each with its own input and output, allowing for simultaneous processing of two separate signals.
• Differential Inputs: Designed to work with differential signals, which helps in minimizing the effects of electromagnetic interference and crosstalk, thereby enhancing the reliability of data transmission over long cable runs.
• High Input Impedance: Its high input impedance ensures minimal loading on the transmission line, preserving signal integrity.
• Wide Supply Voltage Range: Compatible with a broad range of supply voltages, typically from 4.75V to 5.25V, making it suitable for various TTL applications.
• Power-Off Protection: The SN75155D is equipped with power-off protection on inputs and outputs, providing additional safety for connected devices.
• Strobe Function: Each receiver has a strobe function that can disable the output, allowing for multiplexing or for reducing power consumption when the receiver is not in use.

Applications

The SN75155D is commonly used in environments that require reliable data transmission despite the presence of electrical noise. It is ideal for applications such as:

• Telecommunications systems
• Industrial control networks
• Local area networks (LAN)
• Data acquisition systems
• Serial data communication

Quality and Reliability

As with all Texas Instruments products, the SN75155D is manufactured to high standards of quality and reliability. It is available in a standard SOIC-8 package, making it easy to integrate into existing and new designs alike. With its durable construction and proven design, the SN75155D is a reliable choice for engineers and designers looking for a dependable line receiver solution.
