Part Number: PCF8575 Other Parts Discussed in Thread: SN74AHC14 , SN74LVC14A , SN74LV14A Tool/software: Hi,
The PCF8575 datasheet indicates that the I/Os are high at power-on. To prevent any backdriving of the previous circuitry connected to these pins…
Part Number: PCF8575 Tool/software: Hi,
My customer is looking to simulate this device and cannot find the model in PSpice for TI model.
They were wondering if you would be able to share with a .lib or .asy file for this part?
Part Number: PCF8575 Other Parts Discussed in Thread: TCAL6416 , TCA6416A , Tool/software: Hi All,
I have the schematic below to validate.
P0 as output , P1 as input.
At power up I need P0 is not to "0" (ground) otherwise it will be shutoff my…
Part Number: PCF8575 Tool/software: The light does not turn on after the power is powered on or does not turn on for 2 minutes. The replacement of the last batch of materials was found to be back to normal, please help to check the reason, thank you
Part Number: PCF8575 Other Parts Discussed in Thread: LP5009 Tool/software: Can the PCF8575 generate PWM?
Does it have internal clock?
I assume it is possible to generate something like PWM in software, yet this will not be accurate and require…
Part Number: PCF8575 Other Parts Discussed in Thread: TCA6507 Tool/software: Hi TI Technical Support Team,
I have a project where I need to drive SG90 Servo motor (hobby motor). I have to control this motor through I2C interface (this is must). The…
Part Number: AM3358 Other Parts Discussed in Thread: PCF8575 Tool/software: I need to drive some outputs which are connected on gpio-expander. i have PCF8575 and MCP23017 which works pretty well when linux is booted. i need to have ability to drive some…
Part Number: PCF8575 Other Parts Discussed in Thread: TCA9535 , SN74LXC8T245 , TCA9539 I'm currently trying to control an array of MOSFETS so I can drive several solenoids. I'm using the Boron from particle.io as my main board, the PCF8575 as my I/O expander…
Part Number: PCF8575 Dears,
Thanks for your support in advance.
1. Below is the Block Diagram of PCF8575 from datasheet( I marked 1,2,3 three MOSFETS,), in my understanding this P-port is push-pull output (MOSFET2 and MOSFET3),
my question is: when…
Part Number: PCF8575 Other Parts Discussed in Thread: TCA9535 , PCA9535 VCC 3.3V 입력, 포트는 출력 모드로 사용 중이다. 출력 라인에 기본 풀다운 저항(10Kohm)이 있는 경우 높은 출력 레벨은 3.3V가 아닌 약 2V 레벨로 출력됩니다. 무엇이 문제일까요?
