TLC59211: Seeking TLC59211IN alternatives

Part Number: TLC59211
Other Parts Discussed in Thread: TLC59210

Hello,

We use the TLC59211IN sink driver with seven-segment displays in our microcontrollers course. 

Now that it seems to be scheduled for discontinuation, we were hoping to identify a suitable replacement in a DIP package since students need to use it on a breadboard.

Thanks,

Niraj.

    Hi Niraj,

    Sorry for the late reply since I am out of office now. Please give me some time and I will reply to you later.

    Hi Niraj,

    Sorry for late reply.

    Could you please tell me some more detail information? Then I can choose the best solution for you.

    Such as the input voltage, output voltage, output current, interface and any basic information.

    BR, Jared

    Hello Jared,

    EDIT: "into the 8 output channels", not "each of the 8 output channels"

    We're using the TLC59211IN to act as a sink driver for 8 seven segment displays (Vishay TDCR1050M - www.vishay.com/.../tdcx10x0m.pdf).  Each of the displays sinks 175 mA (25 mA x 7 segments) into the 8 output channels.  The TLC59211IN is powered at 3.3V from our STM32F091RCT6-based microcontroller.

    The TLC59211IN inputs are either controlled directly by 8 of the microcontroller's GPIO pins, or controlled by an 8-bit shift register (74HC595) also at 3.3V controlled by SPI pins from the microcontroller.

    Hi Niraj,

    My understanding is that actually you need 8 output channel and each channel can output 25mA with the input voltage 3.3V. Am I correct?

    Hello Jared,

    Yes, that's right.

    Hi Niraj,

    Actually, if you only need the above requirements, I'd like to recommend LP5009 or LP5812 to realize it. I think it would be easier and better than TLC59211.

    Hello Jared,

    I should probably clarify that this chip is being used in our microcontrollers course, where we use it on a breadboard.  SMD/SMT/QFN packages (which are more PCB oriented) will not work - it needs to be in a DIP package so students can push it into a breadboard.

    Are there DIP versions of these chips that we could use?  It also needs to feature a parallel interface (8 pins directly controlling the 8 channels) so that we can use it in conjunction with our shift registers.

    Hi Niraj,

    So you mean that you don't want to change the package drawing and want the same interface?

    Actually, TLC59211 is a bit old device. I am not sure I can find a P2P device to replace it.

    Yes.

    If there's no equivalent, that's alright, and we'll look into changing it up.  However it needs to be a DIP package so it's breadboard compatible.

    If we can leave out the parallel interface, is there any similar DIP-package chip you could suggest to act as a sink driver for 8 seven segment displays?  Would the TLC59210IN work (or will that be discontinued soon as well?)

    Hi Niraj,

    Actually, can I know what do you mean about DIP package?

    For the TLC59210 work time, I am not sure about this but I'd like to suggest you change it first. I will help to find the best solution for your current application.

    If you don't mind, can we contact via email (jared-zhou@ti.com)? Thanks!

    BR, Jared
