Suffix information for Texas Instruments CD74HCT241

I see added suffixes like E and M for the Texas Instruments part number CD74HCT241. What do these call out? Is there a difference between the two parts?

These parts will have the same function and pinout, however, the package style and size will be different.

CD74HCT241M with the M suffix = 20-SOIC (0.295"", 7.50mm Width), which is a surface mount package.

CD74HCT241E with the E suffix = 20-DIP (0.300"", 7.62mm), which is a through hole package.
