SN74HCT273: Electrical characteristics of VOH and VOL

Ryu Yamashita

Part Number: SN74HCT273

Hi team,

I would like to know the value of VOH/VOL when Vcc=5V, IOH/IOL=±10uA.
I'd appreciate it if you could give me a reference value.

Sincerely.
Ryu

VOH = 5 V, VOL = 0 V. See [FAQ] What is the output voltage (VOH or VOL) when the output current is X or the supply voltage is Y?

Hello Yamashita-san,

As Clemens indicated, in most systems the output will be so close to the rail that you probably won't be able to distinguish it from noise - ie the 'high' output will be about 5V, and the 'low' output will be about 0V.

For a more precise value under ideal lab conditions, I would expect a very small voltage drop -- around 250 μV -- so V_OH would be around 4.99975 V, and V_OL would be around 0.00025 V

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
