Part Number: TCA9803 Other Parts Discussed in Thread: TCA9416 , TCA9406 , TS5A3160 We use TCA9803 to achieve I2C level shift from 3.3V(B side) to 1.2/1.8V(A side) ,however A side I2C waveform is abnormal,especially when there are fluctuations in the low…
Part Number: TCA9803 Hi,
For the TCA9803, I 've the below two queries:
Query 1) Apart from 400kHz, can I use 100kHz and 50kHz also. If yes, what should be the pull up resistor value for 400k, 100k and 50k frequencies.
Query 2) As per the datasheet…
Part Number: TCA9803 Hi,
I am using TCA9803 in my PCB for converting 1.8V I2C (at Side A) to 3.3V Level (at Side B) For the calculation of the pull up resistors at the input of the TCA9803 IC, what should I consider:
VCCA = 1.8V or VCCB = 3.3V should…
Part Number: TCA9803 For the TCA9803, I have the below requirements: 1. Four I2C slave devices (Four ICs: ADC IC, GPIO Exp IC, Video Encoder IC, MIPI-DSI to Parallel Converter IC) 2. Trace Length is 35 cm 3. Frequency = 400 kHz
For the TCA9803 I2C Level…
Part Number: TCA9803 Hello, I am using Lantronix QSOM Open-Q 610 uSOM I2C which is at 1.8V. To convert this 1.8V I2C to 3.3V and 2.5V, I am using two TCA9803 ICs.
To a single I2C Rail, I have connected two TCA9803 ICs (one for level shifting 1.8V to…
Part Number: TCA9803 Hi Team, I have connected a I2C bus with 4.7k PU on A side, accidently I have mounted a 10k PU on B side as well. As per datasheet B side has some current source. When 10k was mounted my SoC reset/watchdog was not released many interfaces…
Part Number: TCA9803 Other Parts Discussed in Thread: TCA9617B , Tool/software: Hi!
I'm looking for enhanced pull up to a system with long cable, but sadly other end has to be unbuffered/ up to spec i2c devices. The cable can be between 400 - 2000pF…
Part Number: TCA9803 Other Parts Discussed in Thread: P82B96 Tool/software: Hi,
Custiomer now have a cable product application, and the transmission distance on the I2C bus needs to be larger than 7m. They want to use TCA9803 on the host pcb and the…
Part Number: TCA9803 Other Parts Discussed in Thread: TCA9509 , LSF0002 Hi experts,
May I learn from you do we have I2C buffer support 1.8V(A) <> 1.8V(B) and with package size including pins < 1.5x1.5?
BR,
Allan
