Design a Custom BoardAbout This Component
Octal bidirectional bus transceiver with 3-state outputs, featuring separate output enable (OE) and direction control (DIR) pins. Supports 2.0V to 6.0V supply range with CMOS logic levels and includes input clamp diodes for overvoltage tolerance. Ideal for multiplexed bus applications requiring bidirectional data flow and high-impedance isolation.
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.
