SN74AHC595-Q1: EMI app note and optimized layout

Part Number: SN74AHC595-Q1

Hello,

do you have layout recommendations for the SN74AHC595-Q1 to minimize EMI?

Is there general an app note available about AMC with logic devices?

My customer is using the SN74AHC595-Q1 and he is seeing quite massive emissions from it. It is controlled by a 4MHz clock.

The fast transition makes troubles to him.

Thanks and best regards,

Michael
