74AHC273; 74AHCT273
Octal D-type flip-flop with reset; positive-edge trigger
Rev. 03 — 13 May 2008
Product data sheet
1. General description
The 74AHC273; 74AHCT273 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard
No. 7-A.
The 74AHC273; 74AHCT273 has eight edge-triggered, D-type flip-flops with individual D
inputs and Q outputs.
The common clock (CP) and master reset (MR) inputs, load and reset (clear) all flip-flops
simultaneously.
The state of each D input, one set-up time before the LOW-to-HIGH clock transition, is
transferred to the corresponding output (Qn) of the flip-flop.
All outputs will be forced LOW, independent of clock or data inputs, by a LOW on the MR
input.
The device is useful for applications where only the true output is required and the clock
and master reset are common to all storage elements.

[2] For SO20 packages: above 70 °C the value of Ptot derates linearly at 8 mW/K.
For TSSOP20 packages: above 60 °C the value of Ptot derates linearly at 5.5 mW/K.
For DHVQFN20 packages: above 60 °C the value of Ptot derates linearly at 4.5 mW/K.

[1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
[2] tpd is the same as tPLH and tPHL
.
[3] tpd is the same as tPHL only.
[4] CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × 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 V;
N = number of inputs switching;
Σ(CL × VCC2 × fo) = sum of the outputs.

The term ‘short data sheet’ is explained in section “Definitions”.
The product status of device(s) described in this document may have changed since this document was published and may differ in case of multiple devices. The latest product status
information is available on the Internet at URL http://www.nxp.com.
malfunction of an NXP Semiconductors product can reasonably be expected
15.2 Definitions
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors accepts no liability 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 that such applications will be suitable for the
specified use without further testing or modification.
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.
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.
Terms and conditions of 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, including those pertaining to warranty,
intellectual property rights infringement and limitation of liability, unless
explicitly otherwise agreed to in writing by NXP Semiconductors. In case of
