Design a Custom BoardAbout This Component
Octal buffer and line driver with 3-state outputs, operating from 2V to 6V. Features inverted data outputs with ±6mA drive capability at 5V, 8ns typical propagation delay, and low 80μA maximum quiescent current. Ideal for bus driving and PCB layout with flow-through pinout separating inputs from outputs.
Package: TSSOP-20 (4.4×6.5mm) · 20 pins
Why does this need a breakout?
Hand-soldering 0.65mm pitch leads is tedious and error-prone; a breakout board with standard 0.1" headers lets you prototype I/O expanders and logic gates on breadboards without a reflow oven. The compact SSOP package also becomes DIP-friendly, eliminating jumper spaghetti and reducing assembly mistakes during development cycles.
