Other Parts Discussed in Thread: SN74LV541A-Q1, SN74LVC1G07, SN74LVC2G06-Q1
Hello, my name is Francisco, engineer of the R+D+i Department of the Rother Industries & Technology company.
I would want to use a device through the 3.3V GPIOs signals of my microcontroller enable and disable LEDs. This device and LEDs must be supplied at 5V and they must support a maximum current of 20mA. I have investigated your products and I have found that the Noninverting buffers & drivers would be perfect for controlling LEDs.
In the following document discusses its implementation: https://www.ti.com/lit/an/scaa142/scaa142.pdf?ts=1682579657969&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252Fes-mx%252FSN74LVC1G07
On option that I could use, it would be the SN74ACT244-Q1. I want to ask if this device would be suitable for the previously commented requirements.
Another option but with lower output current (16 mA) is SN74LV541A-Q1, Would this device be suitable?
On the other hand, I would want you to confirm me that I can get outputs of 5V if I apply a 3.3V input to each input pin of SN74ACT244IPWRG4Q1 and SN74LV541A-Q1. Please confirm me both cases, this requirement is fundamental for me. I am not sure about this specifically in the case of SN74LV541A-Q1 because in its datasheet appears the following information that I mark and I attach you.
On the other hand, I would want you to confirm me that the distribution of Leds that I have made it is correct for the SN74ACT244IPWRG4Q1. LEDs enable (0 output) when I apply a low level "0" input and LEDs disable (5 output) when I apply a high level "3.3V" input. I attach an image.
Best regards,
Francisco.
