TIDS8921AM/NOPB
Overview
The DS8921AM/NOPB is a differential line driver and receiver pair designed specifically for full-duplex RS-422 and RS-485 serial data communication. It operates from a 5V supply and provides a robust interface between TTL/CMOS logic levels and differential transmission lines. This transceiver is optimized for high-speed data transmission over long distances in electrically noisy environments.
Why Choose This Part
It features a typical receiver input hysteresis of 70mV to improve noise immunity and prevent false triggering in industrial settings. The SOIC-8 package offers a compact footprint for space-constrained PCB designs while maintaining compatibility with standard 5V logic systems.
Applications
Key Specifications
Getting Started
To evaluate this part, place it on a SOIC-8 breakout board for breadboard prototyping or integrate it directly into a PCB with 100-ohm to 120-ohm termination resistors. Ensure a 0.1uF bypass capacitor is located near the VCC pin and that differential traces are routed with matched lengths for optimal signal integrity.
