SN74LV1T34: Overshoot And Undershoot specification for 2.5V input

Part Number: SN74LV1T34

Hi Dylan,

Thanks for your response. But I need further insight on this.

1. As per your  reply - "Overshoot limit is 5.5v" does it mean that a 2.5v signal can have a overshoot peak upto 5.5V?

2. For undershoot - " undershoot limit is determined by the VIH spec for 3.3 VCC in section 6.5 of the datasheet". The section 6.5 in data sheet specify the High and Low level input voltage (VIH/VIL).How it is related to undershoot?

Please refer the below image for reference.

Sorry if my understand in wrong.

Thanks in Advance,

Ashish

Hi Ashish,

The overshoot limit is 5.5 V and the undershoot limit is determined by the VIH spec for 3.3 VCC in section 6.5 of the datasheet. Yes this device should handle that frequency no problem. Make sure to keep the load capacitance minimal as possible.

Hi,
I am using  SN74LV1T34 Logic level shifter for performing Up Translation from 2.5V to 3.3V.

1. An 2.5V signal from another device is fed to the input pin of SN74LV1T34. I want to know what is the Overshoot and undershoot limit for 2.5V signal at input pin(Pin no. 2).

2. Does 2.5V and 3.3V signal support 25MHz and 50MHz transfer ?

Thanks,

Ashish
