Design a Custom BoardAbout This Component
Octal edge-triggered D-type flip-flop with 3-state outputs designed for bus driving and register applications. Operates from 4.5V to 5.5V with 22ns typical propagation delay and ±6mA output drive. Suitable for buffer registers, I/O ports, and bidirectional bus drivers with TTL-compatible inputs and low 80μA maximum ICC consumption.
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.
