CD74HC4052: quiescence current higher than competion

Part Number: CD74HC4052

I have one question regarding the test measurement of our part:

 

CD74HC4052PW   in TSSOP16 

The following parameter is used in the data sheet
"Iz = Switch ON / OFF Leakage Current" as follows with max. + -2μA:

 

Comparison to Vishay:
For comparison, the data sheet for the Leakage Current is available at Vishay's DG406LE module at max. + -5 nA

the behavior is relatively similar in the two following diagrams
=> Ultimately, the leakage current is determined by the capacitance between the analog inputs and outputs as a function of the frequency.

 

 

TI:                                                                                                      Vishay:

 

Question:
- Can TI tell me on what basis is based this information on the Leakage Current?

  • Hi Kamal,

    If on or off leakage is important to your application, MUX36S16 will be a better candidate when compared with Vishay's DG406. Both TI MUX36S16 and Vishay's DG406 are targeting low leakage use cases, most likely, in industrial sector.

  • In reply to Fan.Wang:

    thank you is it the same test measurement?
  • In reply to Kamal Najmi:

    I am not 100% positive if the test setup is identical since vishay does not draw their test circuit. The test setup of MUX36S16 is illustrated in datasheet. Normally, for leakage test, there should not be too much difference between chip vendors.
