Part Number: SN65C3221

Hi sir,

I want to confirm the pin1 orientation details for SN65C3221DBR SSOP package.

I can find pin1 orientation Q1 mentioned in page 13 of datasheet for TSSOP Package.

But I can not find SSOP package.

So please guide us on this.

Frank,

I have checked with our assembly system to verify that the Pin1 location is the same for the SN65C3221DBR as it is for the SN65C3221PWR package. Using the same orientation as in the image you included, the pin 1 location for SN65C3221DBR is Q1.
