Product data sheet
1. General description
The 74HC14; 74HCT14 is a high-speed Si-gate CMOS device and is pin compatible with
Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard
No. 7A.

CPD is used to determine the dynamic power dissipation (PD in μW):
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 V;
N = number of inputs switching;
∑ (CL × VCC2 × fo) = sum of outputs.

15. Application information
The slow input rise and fall times cause additional power dissipation, this can be
calculated using the following formula:
Padd = fi × (tr × ΔICC(AV) + tf × ΔICC(AV)) × VCC where:
Padd = additional power dissipation (μW);
fi = input frequency (MHz);
tr = rise time (ns); 10 % to 90 %;
tf = fall time (ns); 90 % to 10 %;
ΔICC(AV) = average additional supply current (μA).
Average ΔICC(AV) differs with positive or negative input transitions, as shown in Figure 12
and Figure 13.
An example of a relaxation circuit using the 74HC14; 74HCT14 is shown in Figure 14.

with the same product type number(s) and title. A short data sheet is intended
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 NXP Semiconductors sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
NXP Semiconductors and its customer, unless NXP Semiconductors and
customer have explicitly agreed otherwise in writing. In no event however,
shall an agreement be valid in which the NXP Semiconductors product is
deemed to offer functions and qualities beyond those described in the
Product data sheet.

to the publication hereof.
Suitability for use in automotive applications — This NXP
Semiconductors product has been qualified for use in automotive
applications. The product is not designed, authorized or warranted to be
74HC_HCT14
Product data sheet
suitable for use in medical, military, aircraft, space or life support equipment,
nor in applications where failure or malfunction of an NXP Semiconductors
product can reasonably be expected to result in personal injury, death or
severe property or environmental damage. NXP Semiconductors accepts no
liability for inclusion and/or use of NXP Semiconductors 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. NXP Semiconductors 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 NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors 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.
NXP Semiconductors 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 NXP
Semiconductors 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). NXP 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 — NXP Semiconductors
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nxp.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
