SN74AUP1G126: Operating with VCC of 1.05V (+/-0.05V)

ArTzy

Part Number: SN74AUP1G126

Hi Team,

Can you please share your insights about SN74AUP1G126 operating with Vcc of 1.05(+/-0.05)Vcc:

I am actually concerned with the VIL and VIH of this device. With the given Vcc and its tolerance, since the VIL/VIH is dependent on the VCC, as per datasheet records and using interpolations (as guided HERE), I come up with the following:

So, there would be different VIH(min) and VIL(max).

Question:
Is it recommended to operate the device with such Vcc (including the 0.05V tolerance)?

Regards,
Archie A.

Yes. This device can be operated with any supply voltage between 0.8 V and 3.6 V (see the recommended operating conditions).

Your calculations appear to be correct. The actual input signals will be near the rails (i.e., 0 V and 1.05 V), so in practice, the V_IL/V_IH limits show the noise margin.
