The following part suffixes apply:

No suffix - MIL-STD-883 /2010B Visual Inspection

The 74HC244 is fabricated using a 2.5µm 5V CMOS

process and has the same high speed performance of

LSTTL combined with CMOS low power consumption. The

device can be used as two 4-bit buffers or one 8-bit buffer

and features non-inverting inputs with two output enables,

each controlling four of the 3-state outputs. The device is

specifically designed to improve performance and density in

clock drivers, 3-state memory address drivers and bus

orientated transmitters and receivers. Inputs include clamp

diodes that enable the use of current limiting resistors to

interface inputs to voltages in excess of VCC
