CD4093B: CD4093 specification

Part Number: CD4093B

 We are manufacturing Electronic Ballast. This is the PFC section we are using in our product .

This one is our Regulator circuit diagram. We have highlighted the ic's we are we are using that.

2) Input /output scope captures.

Above is the waveform of the circuit.

    Hello Pooja,
    I see the attached documents. Did you have a question?

    Hello,

    Previously we where using HEF4093BE . but now PHILIPS part is discontinue .So we have ordered equivalent of that CD4093 BE. But that same part is not working in our system. Why is it so? It is just a Nand Gate . Our product is Electronic Ballast
  • In reply to Pooja sapkal:

    I can try to help you narrow down the problem, but we will have to look at exactly what's going wrong.

    Have you done any troubleshooting?
    What do the inputs/outputs to each NAND gate look like on an oscilloscope? Is the NAND gate performing the NAND function?
    We're primarily looking for slow or multiple edges or voltages that don't meet VIH/VIL.

    Hi Emrys,

    We have attached some photos and videos of Drives that we seen on HEF4093 and CD4093. PIC No 1. is Input Drive at Pin No. 1, PIC No. 2. it Pin No. Input Drive at Pin No. 2, PIC No. 3 is Out Put Drive at Pin No. 3.

    Please reply as soon as possible.

    I need to see the inputs and outputs on the same scope shot -- I can't tell anything about the device's operation from separate shots.

    Hi Emrys,

    I have attached to inputs and outputs in the excel file attached below.

    Kindly look into it & provide us a solution for the same.

    Hi Pooja,
    I think there's a disconnect in communication here.

    I need to see the inputs and outputs of the device on the SAME scope shot... The operation of this device depends on the input and output voltages, and the timing of the input signals. On separate displays, I cannot see how the timing is arranged, and I can't tell anything regarding the operation of the device.

    Please see the attachment below.

    Hi Pooja,

    Each scope shot still only has one input or output. I can't tell anything from this.

    Here's an example of a scope shot with both inputs and the output in the same picture:

    It is very easy to see in this shot that there is about 10ns of delay from the trigger of the output to the output actually going low.
