                                                CD4051BCSJX Overview
Shipping overseas is convenient with the electronic component packed in 16-SOIC (0.209, 5.30mm Width). To ensure high reliability, a new packaging method Tape & Reel (TR) is used. A switch device like this is mounted in Surface Mount. In the multiplexer and demultiplexer, 8:1 represents the number of circuits. Operational temperature extended around -55°C~125°C TA. In total, there are 16 terminations. Due to its 8 channels, the electrical component produces high-quality output. Turning on and running the electrical part should be easy with a 5V voltage supply. Into the electrical component body are injected 16 pins. There are 1 circuits in this switch device. Integrated with an analog IC SINGLE-ENDED MULTIPLEXER.
