Ordering Information
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
