SN74AHCT244: what's the difference between SN74AHCT244QPWRQ1 and CAHCT244QPWRG4Q1

Hi Mingmo,

There is no functional difference between these two parts. The "CA" is added to have the device name fit within the website (CA = SN74), because of the "G4" suffix. Please refer to this FAQ: [FAQ] Why does a logic device's part number have an E4/G4 suffix?
