Part Number: PCA9535 Hi,
We have FA return case CPR241100317 CQE ask me post on E2E to you discuss becasue below reason.
Customer reported ~30% failure was observed
All LTCs was shipped to WW customer and there’s no return history
There’s no outlier…
Part Number: PCA9535 When bringing up the PCB that has 3 PCA9535's populated to appx 60C, I am noticing that the I2C line is being driven low before my MCU (master) attempts to communicate with the device.
The MCU is located outside the temperature…
Part Number: PCA9535 Other Parts Discussed in Thread: TCA9535 Tool/software: We make an AM64xx DAQ board that uses the PCA9535.
Our lead customer has discovered that, if a signal is applied to the input pins before VCC is powered up, the output pins…
Part Number: PCA9535 The gpio of pca9535A was pulled down, causing an i2c abnormality
The P6 of the expansion chip was pulled down causing an i2c anomaly
There has been no change in the same design. The customer feedback before that the old batch of…
Part Number: PCA9535 Hi,
I want to ask is there any recommend junction temperature information of PCA9535?
In datasheet only recommend Operating free-air temperature.
Is it feasible if the temperature of the device is 110~120℃? Will it be damaged? Thank…
Part Number: PCA9535 Other Parts Discussed in Thread: TCA9535 HI
In order to hardware reset the PCA9535 registers to default state we are looking to cycle its VCC supply voltage pin resulting in a POR.
Given that all I/O pins will default to high impedance…
Part Number: PCA9535 Other Parts Discussed in Thread: TCA9535 Hi,
PCA9535DBR is EOL, so we are investigating alternatives. What products do you recommend?
Thanks,
Part Number: PCA9535 Other Parts Discussed in Thread: IO-EXPANDER-EVM , TCA9535 Hello,
Can the IO Expander EVM be used to evaluate PCA9535PWR?
Thanks,

Part Number: PCA9535 Hi team,
From datasheet, there is clear spec requirement of I2C input rise and fall time. If the I2C fall and rise time is out of spec, what risk will have? Thanks!
