DESCRIPTION
The 74LVC(H)16374A is a 16-bit edge-triggered flip-flop featuring
separate D-type inputs for each flip-flop and 3-State outputs for bus
oriented applications. The 74LVC16374A consists of 2 sections of
eight positive edge-triggered flip-flops. A clock (CP) input and an
output enable (OE) are provided for each octal. 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 flip-flops will store the state of their individual D-inputs that meet
the set-up and hold time requirements on the LOW-to-HIGH CP
transition.
When OE is LOW, the contents of the flip-flops are available at the
outputs. When OE is HIGH, the outputs go to the high impedance
OFF-state. Operation of the OE input does not affect the state of the
flip-flops.
The 74LVCH16374A bus hold data inputs eliminates the need for
external pull up resistors to hold unused inputs.

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 outputs.
