Design a Custom BoardAbout This Component
Octal bidirectional bus transceiver compatible with TTL and CMOS logic levels. Operates from 4.5V to 5.5V supply and features separate input/output enable controls for each direction. Commonly used for level shifting and bus buffering in microcontroller systems and digital logic circuits.
Package: SSOP-20 (5.3×7.2mm) · 20 pins
Why does this need a breakout?
The 0.65mm pitch and narrow 5.3mm width make hand soldering this SSOP-20 extremely difficult without specialized equipment. A breakout board routes pins to standard 2.54mm headers, enabling breadboard prototyping and eliminating microscopic soldering. Ideal for evaluating microcontrollers and peripheral ICs during development.
