I’m selecting a level shifter for the APA-102 leds. I know that most people successfully (including me) connected it directly to a 3.3V data pin without shifter. However since I’m designing a PCB it might be smart to keep the official specs in account (Adafruit mentions this also with their Dotstar LEDs).
I know the octal shift registers that work like the SN74HCT245 that is used on the FadeCandy board. However I only need one channel (no more ports available at the RFDuino and APA is fast).
Does anyone have experience with this single channel buffer chip from TI: SN74AHCT1G125 ?
