Part Number: TCA9539-Q1 Other Parts Discussed in Thread: TCA9539 , Hi, TI engineers,
We connected tca9539 to i2c0 of tda4ve, and there is still a device max96722 on the bus that can be detected normally, but 9539 has not been detected on the bus. We have…
Part Number: TCA9539 Dear Team,
We've successfully scanned the TCA9539 device but are facing challenges configuring the I/O pins as outputs. Following the datasheet instructions, we attempted to configure P00 to P07 as outputs by writing 0x02 (output…
Part Number: TCA9539 Other Parts Discussed in Thread: TCAL9539 Hi,
I'm using TCA9539QPWRQ1 for my application.
The issue that I have is that TCA9539 is not raising INT when input state is changed.
According to datasheet, steady state of the IOs is…
Part Number: TCA9539 data sheet has following mapping 2 bytes for port 0 and port1. Can TI confirm how port 1 register map (input/output) map to pin P17 to P10?
Using IO expander eval kit https://www.ti.com/lit/ug/slvua59a/slvua59a.pdf, I did a quick…
