Design a Custom BoardAbout This Component
Dual 4-input AND gate logic IC in 14-pin TSSOP surface-mount package. Each gate provides a 4-input AND function with standard logic levels. Operates at 2-6V supply voltage with typical propagation delay under 10ns. Commonly used in digital logic circuits for signal conditioning, control logic, and combinatorial functions in consumer and industrial applications.
Package: TSSOP-14 (4.4×5mm) · 14 pins
Why does this need a breakout?
The 0.65mm pitch on this 14-pin package makes hand soldering tedious and error-prone without magnification and fine tools. A breakout board routes each pin to standard 0.1-inch headers, enabling breadboard prototyping and simplifying connections for LIN transceivers, ADCs, digital potentiometers, and microcontrollers that typically come in this footprint.
