74AHC595; 74AHCT595
8-bit serial-in/serial-out or parallel-out shift register with
output latches; 3-state
Rev. 04 — 11 August 2009
Product data sheet
1. General description
The 74AHC595; 74AHCT595 are high-speed Si-gate CMOS devices and are pin
compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with
JEDEC standard No. 7A.
The 74AHC595; 74AHCT595 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 clock 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 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.

CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi + Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
Σ(CL × VCC2 × fo) = sum of outputs;
CL = output load capacitance in pF;
VCC = supply voltage in V.

Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is 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 NXP Semiconductors sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
16.3 Disclaimers
General — Information in this document is believed to be accurate and
reliable. However, NXP Semiconductors does not give any representations or

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.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) may cause permanent
damage to the device. Limiting values are stress ratings only and operation of
the device at these or any other conditions above those given in the
Characteristics sections of this document is not implied. Exposure to limiting
values for extended periods may affect device reliability.
