TINA/Spice/SN74LVC07A: GPIOs driving through a buffer and output of buffer connected to LEDs for verification of HIGH/LOW state

Emrys,

Thanks for the reply. I will take the GPIO to HIGH state and then observe the LED status which should be lit.
Then again when I take the GPIO to LOW state the LED should be OFF.
Regarding reaching max output current limit on the buffer if I select the resistor in series with the LED to be 500ohm then it will draw only 6.6mA on 3.3V and at any event I wouldn't make more than 2 LEDs ON, considering the SN74LVC07A max current is 50mA

Also, please forward TINA schematic if possible. Thanks

As with most logic devices, there isn't a TINA-TI model for the SN74LVC07A. We do have a plan to generate models for these simple logic devices, however it will probably be the middle of next year before they are available.

I can probably use SN74LVC1G07 Pspice model and build a TINA-TI model myself.
Could you kindly link me to any article or application note where this procedure is given clearly.

Hi Nagendra,
I have asked the TI modelling team to take a look at this thread to see if any of them know of a resource to help you out.
