74HC273; 74HCT273

Octal D-type flip-flop with reset; positive-edge trigger

Rev. 7 — 6 September 2021

Product data sheet

1. General description

The 74HC273; 74HCT273 is an octal positive-edge triggered D-type flip-flop. The device

features clock (CP) and master reset (MR) inputs. The outputs Qn will assume the state of their

corresponding Dn inputs that meet the set-up and hold time requirements on the LOW-to-HIGH

clock (CP) transition. A LOW on MR forces the outputs LOW independently of clock and data

inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface

inputs to voltages in excess of V_CC

.

2. Features and benefits

completing a design.

Nexperia 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 the

customer’s applications and products using Nexperia 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). Nexperia does not accept any

liability in this respect.

[2] The term 'short data sheet' is explained in section "Definitions".

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 https://www.nexperia.com.

Definitions

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 permanently and irreversibly affect

the quality and reliability of the device.

Draft — The document is a draft version only. The content is still under

internal review and subject to formal approval, which may result in

modifications or additions. Nexperia does not give any representations or

warranties as to the accuracy or completeness of information included herein

and shall have no liability for the consequences of use of such information.

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 Nexperia sales

office. In case of any inconsistency or conflict with the short data sheet, the

full data sheet shall prevail.

in a valid written individual agreement. In case an individual agreement is

concluded only the terms and conditions of the respective agreement shall

apply. Nexperia hereby expressly objects to applying the customer’s general

terms and conditions with regard to the purchase of Nexperia products by

customer.

Product specification — The information and data provided in a Product

data sheet shall define the specification of the product as agreed between

Nexperia and its customer, unless Nexperia and customer have explicitly

agreed otherwise in writing. In no event however, shall an agreement be

valid in which the Nexperia product is deemed to offer functions and qualities

beyond those described in the Product data sheet.

No offer to sell or license — Nothing in this document may be interpreted

or construed as an offer to sell products that is open for acceptance or the

grant, conveyance or implication of any license under any copyrights, patents

or other industrial or intellectual property rights.

Export control — This document as well as the item(s) described herein

may be subject to export control regulations. Export might require a prior

automotive applications to automotive specifications and standards,

customer (a) shall use the product without Nexperia’s warranty of the

product for such automotive applications, use and specifications, and (b)

whenever customer uses the product for automotive applications beyond

Nexperia’s specifications such use shall be solely at customer’s own risk,

and (c) customer fully indemnifies Nexperia for any liability, damages or failed

product claims resulting from customer design and use of the product for

automotive applications beyond Nexperia’s standard warranty and Nexperia’s

product specifications.

Notwithstanding any damages that customer might incur for any reason

whatsoever, Nexperia’s aggregate and cumulative liability towards customer

for the products described herein shall be limited in accordance with the
