DESCRIPTION
The74HC/HCT595arehigh-speedSi-gateCMOSdevices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT595 is an 8-stage serial shift register with a
storage register and 3-state outputs. The shift register and
storage register have separate clocks.
Data is shifted on the positive-going transitions of the
SH_CP input. The data in each register is transferred to
the storage register on a positive-going transition of the
ST_CP input. 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 (Q7’) for cascading. It is also provided
with asynchronous reset (active LOW) for all 8 shift
register stages. 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.
QUICK REFERENCE DATA
GND = 0 V; Tamb =25°C; tr=t
f= 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 74HC595 the condition is VI= GND to VCC.
For 74HCT595 the condition is VI= GND to VCC −1.5 V.

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
atthese oratany otherconditionsabovethosegiveninthe
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.
