CD4052B: Analog input signal levels Vs Power Rails

Part Number: CD4052B
Other Parts Discussed in Thread: CD4053B, CD4051B, CD4055B

In reading through the CD4052B datasheet - I noticed that there is no information on how large the analog signal can be relative to the IC power rails. There is only one reference to input voltage signal levels Vs supply voltages (in the ABS-MAX table) - but it only applies to the A, B, C and INH pins.

The cover page of the datasheet implies a +/-20V. "... Analog Signals to 20VP-P (VDD – VEE = 20 V)..."

It's the 20Vp-p that's misleading.

Also, the ABS-MAX for this family (CD4051B, CD4052B, CD4053B) is 20V. Normally, this means VDD should never be this high, unless you want a design with a high infant mortality. What's going on with these devices? What's the recommended operating range for VDD?

Last item: in the ESD Ratings section (page 5) - it lists ESD ratings for the CD4051B and the CD4053B, but not the CD4052B. No ESD protection on the CD4052B?

Thanks!

  • Hi Mark,

    I searched for CD4055B and came across the following similar posts to help you with your questions:

    CD4052B has ESD ratings - I have made a note to include it in the datasheet as well.  It passes 1kV (both HBM and CDM).

    This thread also has the ESD information.

    Please let me know if these help answer your questions.

    Depending on your system's requirements, you may want to look at MUX36D04  or MUX509 in similar configuration, dual rail mux with higher voltage range, higher bandwidth, and less ON-state leakage current. 

    Thanks
