MAX321CUA+ Overview
Presented in 8-TSSOP, 8-MSOP (0.118, 3.00mm Width), this electrical component is convenient for overseas shipping. High reliability is achieved by using advanced packaging method Tube. There is an analog multiplexer mounted in position Surface Mount. In the multiplexer and demultiplexer, 1:1 represents the number of circuits. Temperatures around 0°C~70°C TA are extended for operation. The total number of terminations is 8. High-quality output is provided by the electronic component's 1 channels. A 5V voltage supply should turn on and run the electronic component. As part of the design of the 8 series, this electronic part has been incorporated into the system. Unlike digital switches, these are based on SPST - NC switching circuits. It consists of 2 circuits. Try searching for MAX321 variants of the analog switch ic. The internal resistance of this digital multiplexer is 35Ohm. Datasheets for 8 pin functions are available upon request. Analogue multiplexers of the Dual supply type that are cost-effective. This digital switch can be operated with a current of 1μA. Putting voltage greater than 80μA on the multiplexer may cause damage. For this multiplexer, dual supply voltage is feasible, but it should not exceed 8V. With dual power supplies, you should attach at least 2.7V. There is a voltage range of 8V operating voltages for the electrical part.
