Product data sheet
1. General description
The 74AHC244; 74AHCT244 is a high-speed Si-gate CMOS device.
The 74AHC244; 74AHCT244 has octal non-inverting buffer/line drivers with 3-state
outputs. The 3-state outputs are controlled by the output enable inputs (nOE). A HIGH on
nOE causes the outputs to assume a high-impedance OFF-state.
