SN74AVC4T774: 4V Bus Translator

Edmundo de la Puente

Part Number: SN74AVC4T774

Tool/software:

I'm looking for a bus translator similar to the SN74AVC4T774 but with 4V level support. The 774 supports up to 3.6V on the I/O pins.

Hello Edmundo,

The 774 supports individual IO configurability and this architecture is only supported by AXC and AVC product family (up to 3.6V only)

The best solution I can recommend is using 4x SN74LXC1T45 which supports up to 5.5V signals.

Regards,

Josh

Hi Josh, thanks for the response.

The 145 specs a large switching delay from A to B. For example, at 5V it says min=1ns to max=44ns. Under what conditions you will see this delay change? Is it under full temperature range, voltage range and process variations? What if voltage and temperature were fixed - how much will this delay reduce by?

Hello Edmundo,

We will see worse propagation delay at higher temperatures and lower output voltage.

Q: What if voltage and temperature were fixed - how much will this delay reduce by?

What are the voltage and temperature values you are looking at?

Regards,

Josh
