CD4051B-Q1: Frequency inputs multiplexing with CD4051

Part Number: CD4051B-Q1
Other Parts Discussed in Thread: TS5A23157-Q1, , SN74LVC1G66-Q1

Dear Sir/Madam,

  we are planning to use CD4051 (analog multiplexer/demultiplexer) for frequency input multiplexing. The input range of frequency is 10 KHz max.

Is it possible to connect frequency inputs of 10 KHz to CD4051?  The output will be connected to Timer input of microcontroller. Please suggest compatibility of CD4051 for frequency inputs multiplexing.

 

Regards,

Kumar. A

  • Hi Kumar,

    In terms of 10KHz and your clock mixing application, CD4051B-Q1 should be a good fit. I also have two other devices you may want to consider, TS5A23157-Q1 and SN74LVC1G66-Q1. Based on your supply voltage, input voltage range and channel count, you can compare which one is the best for your design.
