Product specification

Octal buffer/line driver with 5 V tolerant

inputs/outputs (3-state)

74LVC244A; 74LVCH244A

Notes

3. Valid for data inputs of bushold parts (74LVCH244A) only. For data inputs only, control inputs do not have a bushold

circuit.

4. The specified sustaining current at the data inputs do not have a bushold circuit.

5. The specified overdrive current at the data input forces the data input to the opposite logic input state.
