Preliminary
Functional Description
The 74LVT32244 and 74LVTH32244 contain thirty-two
non-inverting buffers with 3-STATE outputs. The device is
nibble (4 bits) controlled with each nibble functioning identi-
cally, but independent of the other. The control pins can be
shorted together to obtain full 32-bit operation. The
Logic Diagrams
3-STATE outputs are controlled by an Output Enable (OEn)
input. When OEn is LOW, the outputs are in the 2-state
mode. When OEn is HIGH, the standard outputs are in the
high impedance mode but this does not interfere with
entering new data into the inputs.
