TISN75176B
Overview
The SN75176B is a versatile, half-duplex differential bus transceiver designed for bidirectional data communication on multipoint transmission lines. It combines a 3-state differential line driver and a differential input line receiver, both operating from a single 5V supply. This device is an industry-standard solution for RS-485 and RS-422 networks, offering robust performance in electrically noisy industrial environments.
Why Choose This Part
The SN75176B features a high receiver input impedance of 12k ohms and a wide common-mode input voltage range of -7V to 12V, ensuring reliable operation despite ground potential shifts. It includes built-in thermal shutdown protection and current limiting for both positive and negative driver outputs, providing essential durability for field-deployed hardware.
Applications
Key Specifications
Getting Started
To use the SN75176B, connect the DE and RE pins to a microcontroller GPIO to toggle between transmit and receive modes. Ensure a 120-ohm termination resistor is placed at the furthest ends of the RS-485 bus to minimize signal reflections. Use a 0.1uF ceramic bypass capacitor close to the VCC pin (pin 8) to maintain signal integrity during high-speed switching.
