Features
Description
• Typical Propagation Delay = 17ns at V
o
= 5V,
The ’HC280 and ’HCT280 are 9-bit odd/even parity, generator
checker devices. Both even and odd parity outputs are
available for checking or generating parity for words up to nine
bits long. Even parity is indicated (ΣE output is high) when an
even number of data inputs is high. Odd parity is indicated
(ΣO output is high) when an odd number of data inputs is
high. Parity checking for words larger than 9 bits can be
accomplished by tying the ΣE output to any input of an
additional HC/HCT280 parity checker.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.

-
please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
