Part Number: TCA9509 During testing of the TCA9509, I found that the input leakage current values for SDAA and SCLA do not match the specifications in the datasheet. My test conditions are as follows:
1. EN = VCCA, VCCA = 1.8V, VCCB = 3.3V, SCLB = 3…
Part Number: TCA9509 I'd like to simulate the I2C waveform of TCA9509 for selecting appropreate pull-up resister.
I already installed PSpice for TI and serached TCA9509 model, but I couldn't find it.
Could you please provide the model or suggest an…

Hi team,
Purpose I would like to confirm whether it is acceptable for Port A of the TCA9509 to be pulled up by a connected device.
Background / Setup
Device: TCA9509
The datasheet states that a pull-up resistor should…
Part Number: TCA9509 Team,
Customer wants to check whether it is swappable between TCA9509DGKR's SDAA and SCLA, just like NXP PCA9509DP,118.
There was a similar E2E discussion but that was 6 years ago so just want to double check. TCA9509: Can SDA…

Tool/software:
for our design we have couple of PCBAs with different voltage rails. I am planning to use TCA9509 to support I2C bus across both boards . I have following I2C tree with 2 options. I would like to know which option…
Part Number: TCA9509 Other Parts Discussed in Thread: TCA9517A , TCA9517 Hi Expert,
My customer wants to confirm that the internal 1mA current source is considered in the IBIS model of the TCA9509? That is, is it already equivalent to include pull-up…
Part Number: TCA9509 Other Parts Discussed in Thread: TCA9517 , TCA9617B Tool/software: Hi Team,
If we are using TCA9509 or TCA9617, it is required to connect port A to port B when using multiple instances. But if we are using TCA9509 with TCA9617,…
Part Number: P82B96 Other Parts Discussed in Thread: TCA9509 , TCA9517 Tool/software: Hello,
After taking over a project halfway through, it seems we have come unstuck by the problem everyone faces using the P82B96, the VOL specification on the S-side…
