Hex inverting Schmitt trigger 74HC14; 74HCT14
FEATURES
•Applications:
– Wave and pulse shapers
– Astable multivibrators
– Monostable multivibrators.
•Complies with JEDEC standard no. 7A
•ESD protection:
HBM EIA/JESD22-A114-A exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V.
•Specified from −40 to +85 °C and −40 to +125 °C.
DESCRIPTION
The74HC14and74HCT14arehigh-speedSi-gateCMOS
devices and are pin compatible with low power Schottky
TTL (LSTTL). They are specified in compliance with
JEDEC standard no. 7A.
The 74HC14 and 74HCT14 provide six inverting buffers
with Schmitt-trigger action. They are capable of
transforming slowly changing input signals into sharply
defined, jitter-free output signals.
QUICK REFERENCE DATA
GND = 0 V; Tamb =25°C; tr= tf= 6 ns
Notes
1. CPD is used to determine the dynamic power dissipation (PDin µW):
PD=C
PD ×VCC2×fi×N+Σ(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 = total load switching outputs;
Σ(CL×VCC2×fo) = sum of the outputs.
2. For type 74HC14 the condition is VI= GND to VCC.
For type 74HCT14 the condition is VI= GND to VCC −1.5 V.

APPLICATION INFORMATION
The slow input rise and fall times cause additional power
dissipation. This can be calculated using the following
formula:
Pad =f
i×(tr×ICC(AV) +t
f×I
CC(AV))×VCC.
Where:
Pad = additional power dissipation (µW);
fi= input frequency (MHz);
tr= input rise time (µs); 10% to 90%;
tf= input fall time (µs); 10% to 90%;
ICC(AV) = average additional supply current (µA).
ICC(AV) differs with positive or negative input transitions, as
shown in Figs 16 and 17.
For 74HC/HCT14 used in a relaxation oscillator circuit,
see Fig.18.

DATA SHEET STATUS
Notes
1. Please consult the most recently issued data sheet before initiating or completing a design.
2. The product status of the device(s) described in this data sheet may have changed since this data sheet was
published. The latest information is available on the Internet at URL http://www.semiconductors.philips.com.
3. For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status.
LEVEL DATA SHEET
STATUS(1) PRODUCT
STATUS(2)(3) DEFINITION
I Objective data Development This data sheet contains data from the objective specification for product
development. Philips Semiconductors reserves the right to change the
specification in any manner without notice.
II Preliminary data Qualification This data sheet contains data from the preliminary specification.
Supplementary data will be published at a later date. Philips
Semiconductors reserves the right to change the specification without
notice, in order to improve the design and supply the best possible
product.
III Product data Production This data sheet contains data from the product specification. Philips
Semiconductors reserves the right to make changes at any time in order
to improve the design, manufacturing and supply. Relevant changes will
be communicated via a Customer Product/Process Change Notification
(CPCN).
DEFINITIONS
Short-form specification The data in a short-form
specification is extracted from a full data sheet with the
same type number and title. For detailed information see
the relevant data sheet or data handbook.
Limiting values definition Limiting values given are in
accordance with the Absolute Maximum Rating System
(IEC 60134). Stress above one or more of the limiting
values may cause permanent damage to the device.
These are stress ratings only and operation of the device
attheseoratanyotherconditionsabovethosegiveninthe
Characteristics sections of the specification is not implied.
Exposure to limiting values for extended periods may
affect device reliability.
Application information Applications that are
described herein for any of these products are for
illustrative purposes only. Philips Semiconductors make
norepresentationorwarrantythatsuchapplicationswillbe
suitable for the specified use without further testing or
modification.
