DESCRIPTION
The 74LVC(H)162244A is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most advanced
CMOS compatible TTL families. Inputs can be driven from either
3.3V or 5V devices. In 3-State operation, outputs can handle 5V.
These features allow the use of these devices in a mixed 3.3V/5V
environment.

The 74LVC(H)162244A is a 16-bit non-inverting buffer/line driver
with 3-State outputs. The device can be used as four 4-bit buffers,
two 8-bit buffers or one 16-bit buffer. 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 74LVC(H)162244A is designed with 30series termination
resistors in both HIGH and LOW output stages to reduce line noise.
The device can be used as four 4-bit buffers, two 8-bit buffers or one
16-bit buffer.

NOTES:
1. CPD is used to determine the dynamic power dissipation (PD in mW):
PD = CPD × VCC2 × fi + S (CL × VCC2 × fo) where:
fi = input frequency in MHz; CL = output load capacity in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
S (CL × VCC2 × fo) = sum of the outputs.
