SN74AUC1G79 Single Positive-Edge-Triggered D-type Flip-Flop
1 Features
3 Description
•
This single positive-edge-triggered D-type flip-flop is
operational at 0.8-V to 2.7-V VCC, but is designed
specifically for 1.65-V to 1.95-V VCC operation.

Latch-Up Performance Exceeds 100 mA Per
JESD 78, Class II
ESD Protection Exceeds JESD 22
– 2000-V Human-Body Model (A114-A)
– 200-V Machine Model (A115-A)
– 1000-V Charged-Device Model (C101)
Available in the Texas Instruments NanoFree™
Package
Optimized for 1.8-V Operation and Is 3.6-V I/O
Tolerant to Support Mixed-Mode Signal Operation
Ioff Supports Partial-Power-Down Mode Operation
Sub-1-V Operable
Max tpd of 1.9 ns at 1.8 V
Low Power Consumption, 10-µA Maximum ICC
±8-mA Output Drive at 1.8 V
When data at the data (D) input meets the setup time
requirement, the data is transferred to the Q output
on the positive-going edge of the clock pulse. Clock
triggering occurs at a voltage level and is not directly
related to the rise time of the clock pulse. Following
the hold-time interval, data at the D input can be
changed without affecting the levels at the outputs.
NanoFree™ package technology is a major
breakthrough in IC packaging concepts, using the die
as the package.
This device is fully specified for partial-power-down
applications using Ioff. The Ioff circuitry disables the
outputs, preventing damaging current backflow
through the device when it is powered down.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.

9.5 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
