SN74AXC1T45: Footprint/Land Pattern Clarification

Renan Santos Adriano

Part Number: SN74AXC1T45

Hi Team,

My customer would like to clarify the Footprint/Land Pattern for our SN74AXC1T45 (SN74AXC1T45DTQR). He exported the .bxl file to Allegro 16.6. He noticed that the pitch/distance between pin 6 and pin 4 is 0.8mm in the datasheet while in the footprint exported it is 0.9mm.

Looking forward to your reply.

Regards,

Hi Renan,

I will have to contact the modeling team on this.

The datasheet will be right most of the times and the .bxl file may need updating.

Hi Renan,

This is the response from the altium team who develops the bxl files.

"Pad 6 & 4 are in irregular shape, was the customer measuring from the pad's center in Y-axis? as the dimensions shows below, the pitch is 1.2-0.4/2=0.8, which matches the drawing."
