Understanding Spec sheet of IC
When a datasheet specifies a current in that way it doesn't mean that is the maximum the chip capability. It means that is the test condition.
The negative sign does indicate the current flow ...

Understanding Spec sheet of IC
The data sheet specifies an output high voltage (probably around 2.4V, because it's a 74LS series). The current given as the current into the chip: a rating of -0.8mA means that the chip can only ...

Contradictory information in current capability of open drain output for the MAX7317 IO expander
The output voltage on the outputs is only guaranteed for sinking current of 6mA or less, so I don’t think this is a useful part for sinking 16mA per output. You would need to add buffers.
It’s ...

Should I use a resistor in series when connecting a pin to logic level high?
On your datasheet, the table on page 7 gives the logic thresholds as low max of 0.4 V, high min of 1.3 V. The absolute max ratings allow 0 to 6 V on PEN2. This means it can be connected directly to a ...

How do you cascade two 7-segment decoder ICs together?
The 74xx47 chip can be configured (with /RBI low) to leave the output blank instead of displaying a zero digit, so that the two-digit output is " 0" instead of "00".
With the "...

Need to find a description for the CSC7102C
According to this Polish electronics forums post, the CSC7102C is a 5V, 3W switching regulator for stepping down line voltage to 5V.
The author of that post couldn't find a datasheet for the CSC7102C, ...

What is the SGMII differential peak to peak voltage?
On Q1: What you've shown for the driver is just one case, the one where Voh is at it's max and Vol is at it's minimum, which will never occur at the same time. The 650 mV output differential voltage ...

Should I use a resistor in series when connecting a pin to logic level high?
For ATE testability, resistors are used, but not necessary for CMOS, otherwise.
However for TTL due to failure modes with reverse Vbe inputs >5.5 V a current limiting 10k resistor can be shared by ...

Contradictory information in current capability of open drain output for the MAX7317 IO expander
it is not clear to me if it can drive simultaneously 8 pins when each pin sinks 16mA. I don't have a lot of options because I need SPI.
It's not a typo but a guaranteed current limit maximum on Data ...

Understanding Spec sheet of IC
Old school TTL was designed to switch with higher current with low logic "0" levels (e.g. 16 mA max ) and similarly needed more current for low-level input. Thus true to each TTL family ...

Understanding Spec sheet of IC
The minus sign in front just means the direction of current.
In this case it means the chip can source (push out) 0.8mA maximum from output pin.
Without minus sign, it means the chip can sink (pull in)...
