74F280B Datasheet (Philips) - 9-bit odd/even parity generator/checker

74F280B, 9-bit odd/even parity generator/checker

The 74F280B is a 9-bit Parity Generator or Checker commonly 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 whe
