BU4551BF-E2 Overview
This electronic part is conveniently packaged in 16-SOIC (0.173, 4.40mm Width), making it easy to ship abroad. In order to provide high reliability, an advanced packaging method Tape & Reel (TR) is used. Multiplexers like this are mounted in the Surface Mount position. There is 2:1 ratio between the number of multiplexers and demultiplexers. Operation at a temperature around -40°C~85°C TA. Total terminations are 16. The electronic part provides high-quality output because it has 2 channels. When the electronic component is given a voltage of 5V, it should be turned on and run. As part of the design of the 16 series, this electronic part has been incorporated into the system. The analog switch ics are built using SPDT switching circuits. This multiplexer is composed of 4 circuits. Try searching with BU4551B if you're looking for variants. The internal resistance of this digital multiplexer is 280Ohm. The datasheets for the 16 pins explain the functions. A analogue multiplexer of this type is a Multiplexer or Switches. In a normalsituation, users should not supply the switches with voltage higher than 16V. Analogue multiplexers of the Single supply type that are cost-effective. The lowest voltage the electronic part should receive is 3V. 15μA current would be enough for this multiplexer to operate. The voltage required by this switch device is 3V~16V, draining from a single voltage supply. There's no problem with dual supply voltage for this switch device. However, it shouldn't exceed 8V. In the case of dual power supplies, you should connect at least 1.5V. There is an analog IC DIFFERENTIAL MULTIPLEXER integrated with this board. The analog switch ic utilizes SEPARATE OUTPUT outputs in total. The transfer of data can be performed over 15MHz bandwidths.
