SN74HCS00-Q1: Input threshold temperature variations

Ivan Goncharov

Part Number: SN74HCS00-Q1
Other Parts Discussed in Thread: SN74HCS72-Q1,

Hi, TI experts!

Datasheets for SN74HCS00-Q1 and SN74HCS72-Q1 provide input high and low thresholds variations but only for 25 degrees.

Could you help me to estimate minimum high and maximum low input levels to provide robust switching in temperature range from -40 to +105 degrees please?

    Hey Ivan,

    This is in the datasheet in the Electrical Characteristics table. The electrical characteristics are across the temperature range they're rated at (-40 to +125C). I've highlighted this in yellow below. The datasheets state that the typical ratings are the only ones measured at 25C.  I've underlined this portion in red.


    Thanks,
    Rami
