74HC280; 74HCT280

9-bit odd/even parity generator/checker

Rev. 4 — 16 August 2021

Product data sheet

1. General description

The 74HC280; 74HCT280 is a 9-bit parity generator or checker. Both even and odd parity outputs

are available. The even parity output (PE) is HIGH when an even number of data inputs (I0 to I8)

is HIGH. The odd parity output (PO) is HIGH when an odd number of data inputs are HIGH.

Expansion to larger word sizes is accomplished by tying the even outputs (PE) of up to nine

parallel devices to the final stage data inputs. Inputs include clamp diodes. It enables the use of

current limiting resistors to interface inputs to voltages in excess of V_CC

2. Features and benefits

•

Word-length easily expanded by cascading

•

Generates either odd or even parity for nine data bits

Wide supply voltage range from 2.0 to 6.0 V

Input levels:

•

For 74HC280: CMOS level

For 74HCT280: TTL level

•

CMOS low power dissipation

High noise immunity

Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Complies with JEDEC standards

•

JESD8C (2.7 V to 3.6 V)

JESD7A (2.0 V to 6.0 V)

•

ESD protection:

•

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.

Terms and conditions of commercial sale — Nexperia products are

sold subject to the general terms and conditions of commercial sale, as

published at http://www.nexperia.com/profile/terms, unless otherwise agreed

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

authorization from competent authorities.

Disclaimers

Limited warranty and liability — Information in this document is believed

to be accurate and reliable. However, Nexperia does not give any

representations or warranties, expressed or implied, as to the accuracy

or completeness of such information and shall have no liability for the

consequences of use of such information. Nexperia takes no responsibility

for the content in this document if provided by an information source outside

of Nexperia.

Non-automotive qualified products — Unless this data sheet expressly
