74LVC74A
Dual D-type flip-flop with set and reset; positive-edge trigger
Rev. 7 — 20 November 2012
Product data sheet
1. General description
The 74LVC74A is a dual edge triggered D-type flip-flop with individual data (nD) inputs,
clock (nCP) inputs, set (nSD) and (nRD) inputs, and complementary nQ and nQ outputs.
The set and reset are asynchronous active LOW inputs and operate independently of the
clock input. Information on the data input is transferred to the nQ output on the
LOW-to-HIGH transition of the clock pulse. The nD inputs must be stable one set-up time
prior to the LOW-to-HIGH clock transition, for predictable operation.
Schmitt trigger action at all inputs makes the circuit highly tolerant of slower input rise and
fall times.
2. Features and benefits
5 V tolerant inputs for interlacing with 5 V logic
Wide supply voltage range from 1.2 V to 3.6 V
CMOS low power consumption
Direct interface with TTL levels
Complies with JEDEC standard:
JESD8-7A (1.65 V to 1.95 V)
JESD8-5A (2.3 V to 2.7 V)
JESD8-C/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-B exceeds 200 V
CDM JESD22-C101E exceeds 1000 V
Specified from 40 C to +85 C and 40 C to +125 C

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.

CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD VCC2 fi N + (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 = number of inputs switching
(CL VCC2 fo) = sum of the outputs

for quick reference only and should not be relied upon to contain detailed and
full information. For detailed and full information see the relevant full data
sheet, which is available on request via the local Nexperia sales
office. In case of any inconsistency or conflict with the short data sheet, the

Product data sheet
Suitability for use — Nexperia products are not designed,
authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of a Nexperia product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. Nexperia and its suppliers accept no liability for
inclusion and/or use of Nexperia products in such equipment or
applications and therefore such inclusion and/or use is at the customer’s own
risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. Nexperia makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using Nexperia products, and Nexperia
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the Nexperia
product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
Nexperia does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using Nexperia
products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). Nexperia does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Terms and conditions of commercial sale — Nexperia
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nexperia.com/profile/terms, unless otherwise
agreed in a valid written individual agreement. In case an individual
agreement is concluded only the terms and conditions of the respective
agreement shall apply. Nexperia hereby expressly objects to
applying the customer’s general terms and conditions with regard to the
purchase of Nexperia products by customer.
No offer to sell or license — Nothing in this document may be interpreted or
construed as an offer to sell products that is open for acceptance or the grant,
conveyance or implication of any license under any copyrights, patents or
other industrial or intellectual property rights.
