尝试解决1:加上拉电阻 如果只是100uA的逻辑输出能力,这里就基本可以看成是open-drain输出结构了(相对Darlington管的驱动需求来说)。所以我在GPIO上加了个1K的上拉电阻,实测电压2.8V,驱动逻辑完全正常了。(可以大概计算管子需求的电流在600uA左右) 但是,设计之初默认是所有relay都不开启,加上拉之后就变成了所有relay...
Just want to confirm with you if LP8866S-Q1 I2C pins OD or push-pull? Customer need this info for an issue shooting in system. Thanks. Johnny 2 年多前 +1Zhiqian Wu2 年多前 TI__Mastermind22695points Hi, Johnny SDA pin is open-drain. SCL is an input pin...
Part Number: TXS0108E Hi Team, Our customer is looking for a level shifter that can support both I2C (open drain) and I2S (push/pull). He is considering the TXS0108E

The I2C bus master output can be push-pull or open-drain (pull-up resistors may be required) and the I2C bus device output can be totem pole or open-drain (pull-up resistors are required to pull the SCL2 and SDA2 outputs to VDPU). However, if either output is push-pull, data ...
Four push-pull outputs with selectable power-up default levels. PCF8574-, PCF8574A-compatible versions: Eight open-drain I/O ports with nonlatching transition — detection interrupt and pullups on all ports. All ports power up as inputs (or logic-high outputs). Any port can be used as ...
