Part Number: TCA9536 Other Parts Discussed in Thread: TCA9534 , PCA9534 HI ,
I will use the Arduino UNO R3 EVB to control the TCA9536,
Please share any source code for I2C control for reference.
Part Number: TCA9536 Hi team,
In the typical application of the datasheet, there is no capacitor between VCC to GND.
However, on the EVM, there is a capacitor, 100nF.
Would you typically recommend a capacitor here? which design should customer follow…
Part Number: TCA9536 Other Parts Discussed in Thread: TCA9543A , TCA9545A Hi,
I see that there are four (4) variants of TCA9536, each with their own unique device address. I would like to use one of each variant on an I2C bus, and I see that there is an…
Part Number: TCA9536 Hi Experts,
My customer wants to output logic Low on P0 pin when power-on. Since the initial state is that internal FET Q1 and Q2 is off and 100K PU resister is enabled, is it OK to use external pull-down resister like 4.7k ohm?
…
Part Number: TCA9536 Other Parts Discussed in Thread: PCA9536 Hello,
I have noticed that when I write to registers 0x01, 0x02, and 0x03, it does not seem like the first 4 bits are being overwritten. Just the second 4 bits are modified. The unmodified…
Part Number: TCA9536 Hi
TCA9536 has A, B and C options to support different address in SON package. Will it have VSSOP package for 3 different address?
Part Number: TCA9536 Hello Sir,
We would like to use TCA9536 in our design for I2C-GPIO expansion. It will share the I2C bus with one on-board EEPROM. Please help on the questions below.
1. The expanded 4 GPIOs (P0-P3) will be always in output state to…
Part Number: TCA9536 Hi staff
Handling of unused pins.
Currently unused pins are open. Is there any recommended connection method such as wiring unused pins to the ground?
Unused pins are P1 and P2. (We are considering whether P3 is unnecessary.)

Part Number: TCA9536 Other Parts Discussed in Thread: PCA9536 , Dear all,
May I check with you if TCA9536 VSSOP package can directly replace NXP PCA9536 TSSOP package without modifying the footprint?
If not, would it be possible to do the co-layout for…
