DESCRIPTION
The 74LVC1G80 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 3.3 V or 5 V devices. This
feature allows the use of this device in a mixed
3.3 V and 5 V environment.
This device is fully specified for partial power-down
applications using Ioff. The Ioff circuitry disables the output,
preventing the damaging backflow current through the
device when it is powered down.
The 74LVC1G80 provides a single positive-edge triggered
D-type flip-flop.
Information on the data input is transferred to the Q output
pin on the LOW-to-HIGH transition of the clock pulse.
The input pin D must be stable one set-up time prior to the
LOW-to-HIGH clock transition for predictable operation.

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.
