Design a Custom BoardAbout This Component
Synchronous presettable 4-bit binary counter with asynchronous reset and look-ahead carry for cascading. Features parallel load capability, dual count enable inputs (CEP, CET), and terminal count output. Operates from 2.0V to 6.0V with CMOS low power dissipation and positive-edge triggered clock. Ideal for frequency division, timing circuits, and multi-stage counter cascades.
Package: SOIC-16 (3.9×9.9mm) · 16 pins
Why does this need a breakout?
The 1.27mm pin pitch on this 16-pin package makes hand-soldering impractical and breadboard mounting impossible. A breakout board brings the pins to standard 2.54mm spacing, enabling quick prototyping of RS-232/RS-485 transceivers, ADCs, and line drivers without requiring surface-mount soldering skills or PCB fabrication.
