Functional Description
The 74ALVCH16244 contains sixteen non-inverting buffers
with 3-STATE outputs. The device is nibble (4 bits) con-
trolled with each nibble functioning identically, but indepen-
dent of each other. The control pins may be shorted
together to obtain full 16-bit operation.The 3-STATE out-

puts are controlled by an Output Enable (OE_n) input. When
OE_n is LOW, the outputs are in the 2-state mode. When
OE_n is HIGH, the standard outputs are in the high imped-
ance mode but this does not interfere with entering new
data into the inputs.
