  • Dear Sir,

     

    I will be highly greatful to you if you can provide any ingormation on 7 segment 4 digit 28 pins LCD Decoder driver. I am in great need of this. If possible can you suggest some 7 segment LED decoder driver also. It would be nice of you if you can help me in this.

     

    With Regards

    Good Day,

     

    I am sorry that I did not see this question from a month ago and LCD drivers are not exactly my strong point, but I will do my best to help. I can certainly recommend some products, but I do not know just what kind of information you need besides that.

     

    If your LCD is miltiplexed, you can use any of these decoder/drivers:

    HCF4543B from SGS Thompson Microelectronics

    CD4511B from Texas Instruments

    MAX7231, MAX7232, MAX7233 and MAX7234 from Maxim Integrated Products

     

    If your display is not multiplexed but has separate pins for each segment, finding a driver for it is more difficult. The only device that I am aware of that will easily do the job is the PT6530 from Princeton Technology in Taiwan, although this device has more capability than you really need and comes in a rather large package. But, with a little ingenuity you can probably get the above multiplexed devices to do the job.

     

    If you tell me a little more about just what information you need and the part type of the display you are using, I might be able to offer more help. At least, I hope so.
