SOT353 package.
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 or 5 V devices. This
feature allows the use of this device in a mixed 3.3 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
on the LOW-to-HIGH transition of the clock pulse.
The D input must be stable one set-up time prior to the
LOW-to-HIGH clock transition for predictable operation.
QUICK REFERENCE DATA
GND = 0 V; Tamb =25 °C; tr =tf ≤ 2.5 ns.
Note
1. CPD is used to determine the dynamic power dissipation (PD in W).
PD =CPD × VCC2 × fi +(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.
