Design a Custom BoardAbout This Component
Octal bus transceiver with three-state outputs for 2V to 6V operation. Features independent transmit and receive paths with directional control via OE pin. Commonly used for bidirectional data bus buffering, level shifting, and isolation in microcontroller and digital logic circuits operating at mixed voltage levels.
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.
