Hi Team,
Our customer would like to know how much extra current (Icc) will be added when the input to SN74LVC1T45DCKR is in between high and low and if it is okay to keep the input in the middle of the supply voltage all the time.
Thank you for your support!
Regards,
Danilo
Typically several milliamperes (there is no guaranteed limit):
The Δt/Δv limit must not be exceeded; see [FAQ] How does a slow or floating input affect a CMOS device?
Adding a Schmitt-trigger buffer (e.g., SN74LVC1G17) allows such signals, but does not reduce the power consumption. For truly analog signals, it would be a better idea to use a comparator (e.g., TLV7011, TLV4041).
Hi Rami and Clemens,
According to the customer the figure below indicates some hysteresis, but another figure shows oscillations. Which is the case for LVC, or is it temperature dependent?
Regards,
Danilo
