DESCRIPTION
The 74LVQ280 is a low voltage CMOS 9 BIT
PARITY GENERATOR fabricated with sub-micron
silicon gate and double-layer metal wiring C
technology. It is ideal for low power and low noise
3.3V applications.
It is composed of nine data inputs (A to I) and odd/
even parity outputs ( ODD and EVEN). The nine

data inputs control the output conditions. When
the number of high level input is odd,
output is kept high and EVEN output low.
Conversely, when the number of high level is
even, EVEN output is kept high and ODD low.
The IC generates either odd or even parity making
it flexible application. The word-length capability is
easily expanded by cascading.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
