As the electronic part is packed in 16-TSSOP (0.173, 4.40mm Width), international shipping is convenient. To ensure high reliability, a new packaging method Tape & Reel (TR) is used. Mounted in Surface Mount is this multiplexer. Multiplexer and demultiplexer circuits have a number 2:1. The operating temperature is extended to around -55°C~125°C. Totally, there are 16 terminations. The electronic part provides high-quality output because it has 1 channels. In the case of a voltage supply of 5V volts, the electrical part can be powered up and run. A total of 16 pins are injected into the electrical part body. SPDT switching circuits are used in these analog switch ics. Circuits number 2 make up this analogue multiplexer.
