Description
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 (
E output is high) when an
even number of data inputs is high. Odd parity is indicated
(
O 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
E output to any input of an
additional HC/HCT280 parity checker.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
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.

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)
