Part Number: PCA9536 Hi,
Is my understanding correct that the unused pins for P0, P1, P2 and P3 shouldn't be kept floating since each port pin is enabled as an input with high-impedance in the default setting? If yes, should the pull-down resistors be…
Part Number: PCA9536 Sir,
I have a question about PCA9536 power-on reset, if register values are incorrect, is it safe if write all regs right (software reset?) after power up to make sure the value is correct?
what's the different between power-on reset…
Part Number: PCA9536 Hi,
Could you please tell me the update rate for P0 ~ P3 if using PCA9536 at 100-kHz in the standard mode and alternately writing 0 and 1 to the polarity Inversion register? What is the maximum update rate when using only P0?
Best…
Part Number: PCA9536 Hi team,
Customer want to use GSBGA PCA9536 due to their limited space, however, I find our datasheet didn't get a part of GSBGA package there, could you suggest if there is a GSBGA PCA9536 part that customer could use? And what's…
Part Number: PCA9536 Hello E2E,
What is P-port status as default?
I saw the description in datasheet that the default is input with high-Z mode in p.16, but i could see the internal pull-high 100k in figure 17.
Which one is correct?
In system requirement…
