Design a Custom BoardAbout This Component
Octal bidirectional bus transceiver in 20-SOIC package for interfacing between data busses. Operates at 4.5-5.5V with TTL-compatible inputs, 11ns typical propagation delay, and low power CMOS dissipation. Features direction control via DIR input and output enable for bus isolation. Suitable for asynchronous inter-bus communication in digital systems.
Package: SOIC-20W (7.5mm wide) · 20 pins
Why does this need a breakout?
The 1.27mm pin pitch makes hand-soldering this 20-pin SOIC challenging and error-prone. A breakout board brings all pins to standard 0.1" spacing, enabling reliable breadboard prototyping and simplifying development of USB-to-UART interfaces without requiring reflow soldering or specialized equipment.
