SN74AXC4T245: VOH, VOL Values at 1.8V VCCI

Abhijith TP

Part Number: SN74AXC4T245

Tool/software:

Dear Team,

As per the datasheet of SN74AXC4T245RSVR level translator IC, the VOH and VOL values are provided for 1.65V and next voltage is 2.3V, But in our application we are providing a 1.8V at VCCI.

Could you please provide us with the VOH and VOL values for 1.8V at VCCI?

Regards,

Abhijith

Hello Abhijith,

Please take a look at this FAQ

[FAQ] How do I determine the output voltage (VOH, VOL) or output current (IOH, IOL) of a CMOS logic device?

Regards,

Josh

The specifications are for lower supply voltages to account for tolerances; it's the worst case of a 1.8 V ± 0.15 V supply.
Use the V_OL value specified for 1.65 V. Add 0.15 V to the V_OH value.
