74HC244DGeneral description
The 74HC244; 74HCT244 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL (LSTTL).
The 74HC244; 74HCT244 has octal non-inverting buffer/line drivers 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 74HC244;
74HCT244 is identical to the 74HC240; 74HCT240 but has non-inverting outputs.
