TECHNICAL DATA
KK74LV244
OCTAL BUFFER/LINE DRIVE; 3-STATE
The KK74LV244 is a low-voltage Si-gate CMOS device and is pin and
function compatible with KK74HC/HCT244.
The KK74LV244 is an octal non-inverting buffer/line driver with 3-state
outputs. The 3-state outputs are controlled by the output enable inputs 1OE
and 2OE. A HIGH on nOE causes the outputs to assume a high impedance
OFF-state.
The KK74LV244 is identical to the KK74LV240 but has non-inverting
outputs.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or
VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
