SN74LVT16244B: The differences for SN74LVT16244BDGGR and 74LVT16244BDGGRG4

Part Number: SN74LVT16244B

Hi team,

The customer needs to get the differences for  SN74LVT16244BDGGR and 74LVT16244BDGGRG4. 

But the electrical parameters and the package are the same from the datasheet for the two devices. 

He confuses if the electrical parameters and the package  are the same for the two IC number devices,

why there are still two different IC numbers? Would you explain this?

Best Wishes,

    Hi Mickey,

    Historically, G4 and E4 suffixes meant that the devices were rated to be “Green” or “Lead Free.” However, as time has passed, all devices have been pushed to these new “Green” or “Lead Free” standards, but the specific part orderables have remained available so that customers have had a consistent orderable part number. The SN was probably dropped due to the fact that the part number is so long. These devices are the same.
