DESCRIPTION
The 74ALVC244 is a high-performance, low-power,
low-voltage, Si-gate CMOS device and superior to most
advanced CMOS compatible TTL families.
The 74ALVC244 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. Schmitt-trigger action at all inputs makes the
circuit highly tolerant for slower input rise and fall times.

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts;
N = total load switching outputs;
Σ(CL × VCC2 × fo) = sum of the outputs.
2. The condition is VI = GND to VCC.
