• Manufacturer Part Number: 74lvth32244
• Description: Voltage 32-bit Buffer/line Driver With 3-state Outputs Preliminary
• Manufacturer: Fairchild Semiconductor

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
