1. General description
The 74HC595; 74HCT595 ar e hig h-sp eed Si-g ate CMOS d evices and ar e pin compatible
with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC
standard No. 7A.
The 74HC595; 74HCT595 are 8-stage serial shift registers with a storage register and
3-state outputs. The registers have separate clocks.
Data is shifted on the positive-going transitions of the shift register clock input (SHCP).
The data in each register is transferred to the storage register on a positive-going
transition of the storage register clo ck input (STCP). If both clocks are connected together,
the shift register will always be one clock pulse ahead of the storage register.
The shift register has a serial input (DS) and a serial standard output (Q7S) for cascading.
It is also provided with asynchronou s reset (acti ve LOW) for all 8 shif t register st ages. The
storage register has 8 parallel 3-state bus driver outputs. Data in the storage register
appears at the output whenever the output enable input (OE) is LOW.
2. Features and benefits

Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and tit le. A short data sh eet is intended
for quick reference only and shou ld not be rel ied u pon to cont ain det ailed 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 pre vail.
Product specificat ionThe 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 off er functions and qualities beyond those described in the
Product data sheet.

Right to make changes — NXP Semiconductors reserves the right to make
changes to information published in this document, including without
limitation specifications and product descriptions, at any time and without
notice. This document supersedes and replaces all informa tion supplied prior
to the publication hereof .
Suitability for use — NXP Semiconductors products are not designed,
authorized or warranted to be suit able 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 perso nal injury, death or severe property or environmental
damage. NXP Semiconductors accepts no liab ility 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 tha t such application s will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and ope ration of their applications
and products using NXP Semiconductors product s, and NXP Semiconductors
accepts no liability for any assistance with applications or cust omer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suit able and fit for the custome r’s applications and
products planned, as well as fo r 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 th e 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 permanent ly 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 individua l agreement. In case an individual
agreement is concluded only the ter ms and conditions of the respective
agreement shall apply. NXP Semiconductors hereby expressly objects to
applying the customer’s general terms and conditions with regard to the
purchase of NXP Semiconductors products by customer.
