74F280B Description
The 74F280B is a 9-bit Parity Generator or Checker monly used to detect errors in high speed data transmission or data retrieval systems. Both Even (∑E) and Odd (∑O) parity outputs are available for generating or checking even or odd parity on up to 9 bits. The Even (∑E) parity output is High when an even number of Data inputs (I0 - I8) are High.
74F280B Key Features
- High-impedance NPN base inputs for reduced loading
