SN74LV244A: Input voltage requirement

Emma Wang

Part Number: SN74LV244A

Hi expert,

I found the input creteria is shown as:

so how about the input voltage above 0.3VCC and below 0.7VCC?

Is it not sure?

so does it mean we need customer to restrict their input voltage?

Voltages between these thresholds are invalid and must happen only for a short time during switching.

See the Δt/Δv limit in the Recommended Operating Conditions, and [FAQ] How does a slow or floating input affect a CMOS device?
