74LV244D: Octal buffer/line driver (3-state)

The 74LV244 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC244 and 74HCT244.

The 74LV244 is an octal non-inverting buffer/line driver with 3-state outputs. The output enable inputs 1OE and 2OE control the 3-state outputs. A HIGH on nOE causes the outputs to assume a high impedance OFF-state. The 74LV244 is identical to the 74LV240 but has non-inverting outputs.
