This sounds like correct operation of the device.
If VCCP falls below the operation voltage of 1.65V, then behavior is not characterized for the device.
Has this issue been repeated on multiple TCA6424A's?
Hi User6448843,
user6448843 said: Does this mean that the bus can be used immediately after reset?
You are correct.
Technically speaking, as soon as /RESET passes the 0.7 x VCCI = VIH threshold, the /RESET condition is released, and the bus can be used…
User6448843,
TCA6424A can support 400 kHz.
I don't know the specific differences between the V2.0 or V3.1 spec.
From a data frame perspective, TCA6424A can interpret SMBus messages following the start, byte, ack/nack, stop format. TCA6424A would not…
Other Parts Discussed in Thread: TCA6424A , TMAG5231 Tool/software: Hello,
I have a circuit in which I have 2 TMAG5231 sensors connected in a diode-or configuration and the output is going to a pin of the TCA6424A. The or circuit has an 10k external pullup…
Part Number: TCA6424A Tool/software: ◆Question
If SDA is an output, please tell me the standard values (electrical characteristics) of VOH and VOL.
※ It seems that this is not stated in the TCA6424A data sheet.
Best regards
Part Number: TCA6424A Tool/software: ◆Question
Is it okay to use this circuit for unused ports? (Does it need to be connected to VCCI or GND?)
In Table 5-1. Pin Functions, it is set as an input at power up.
Best regards
Part Number: TCA6424A Tool/software: We have changed one 8 port i2c gpio expander TCA6408ARGTR o 24 port gpio expander TCA6424ARGJR. How much current increment should we expect?
All the gpios is set to output, either output high or low. Almost all of them…
Part Number: TCA6424A Tool/software: Hi,
what state should the unsed pin be? is it ok to keep them floating or will it cause false INT? optimal state to save power.
Thanks.
