74HC14; 74HCT14

Hex inverting Schmitt trigger

Rev. 8 — 22 May 2020 Product data sheet

1. General description

The 74HC14; 74HCT14 is a hex inverter with Schmitt-trigger inputs. This device features reduced

input threshold levels to allow interfacing to TTL logic levels. Inputs also 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

•Complies with JEDEC standard no. 7A

•Low-power dissipation

•ESD protection:

•HBM JESD22-A114F exceeds 2000 V

•MM JESD22-A115-A exceeds 200 V

•Multiple package options

•Specified from -40 °C to +85 °C and from -40 °C to +125 °C

3. Applications

•Wave and pulse shapers

•Astable multivibrators

•Monostable multivibrators

13. 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 Fig. 12 and Fig. 13.

An example of a relaxation circuit using the 74HC14; 74HCT14 is shown in Fig. 14.

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 Nexperia 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

Nexperia and its customer, unless Nexperia and customer have explicitly

agreed otherwise in writing. In no event however, shall an agreement be

valid in which the Nexperia product is deemed to offer functions and qualities

beyond those described in the Product data sheet.

Disclaimers

Limited warranty and liability — Information in this document is believed

In no event shall Nexperia be liable for any indirect, incidental, punitive,

special or consequential damages (including - without limitation - lost

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 an 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

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
