74HC3G14; 74HCT3G14
Triple inverting Schmitt trigger
Rev. 5 — 9 December 2013
Product data sheet
1. General description
The 74HC3G14; 74HCT3G14 is a triple inverter with Schmitt-trigger inputs. Inputs include
clamp diodes. This enables the use of current limiting resistors to interface inputs to
voltages in excess of VCC. Schmitt trigger inputs transform slowly changing input signals
into sharply defined jitter-free output signals.
2. Features and benefits
Wide supply voltage range from 2.0 V to 6.0 V
Complies with JEDEC standard no. 7A
Input levels:
For 74HC3G14: CMOS level
For 74HCT3G14: TTL level
High noise immunity
Low power dissipation
Balanced propagation delays
Unlimited input rise and fall times
Multiple package options
ESD protection:
HBM JESD22-A114E exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Specified from 40 C to +85 C and 40 C to +125 C
3. Applications
Wave and pulse shaper for highly noisy environments
Astable multivibrators
Monostable multivibrators

14. Application information
The slow input rise and fall times cause additional power dissipation, which can be
calculated using the following formula:
Padd = fi (tr ICC(AV) + tf ICC(AV)) VCC where:
Padd = additional power dissipation (W);
fi = input frequency (MHz);
tr = input rise time (ns); 10 % to 90 %;
tf = input fall time (ns); 90 % to 10 %;
ICC(AV) = average additional supply current (A).
ICC(AV) differs with positive or negative input transitions, as shown in Figure 12 and
Figure 13.
An example of a relaxation circuit using the 74HC3G14/74HCT3G14 is shown
in Figure 14.

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
Suitability for use — NXP Semiconductors 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 an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept 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
