1. general 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.
