Hi all,

I would like to ask about I2C characteristics.

DIGITAL OUTPUT SIGNAL nINT, SDA Vol=0.4 V test condition is described as Isource=2 mA.

Can TI's LP8758A2B4YFFR be set to IOL3mA (min) and VOL=0.4 V (min) according to I2C bus specifications?

Best Regards,

Ryusuke

Hi Ryusuke,

Could you elaborate on what you mean here by 'min', seen in below quote? The 0.4V for this column specifically denotes MAX so I am a little confused by your question.

And are you talking about both pins or just SDA?

Thanks,
Field

Hi Field,

Thank you fou your reply.

Sorry. Because I am comparing with NXP UM10204, I wrote (Min).

I2C-bus specification and user manual (nxp.com)

I would like to confirm if I can recognize TI LP8758A2B4YFFR as a similar spec.

I would appreciate it if you could comment on SCL and SDA for comparison.

Best Regards,

Ryusuke

Yes, I believe the device should be capable of this.
