DESCRIPTION

The 74F280A 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.

FEATURES

• High-impedance NPN base inputs for reduced loading (20µA in Low and High states)

• Buffered inputs — one normalized load

• Word length easily expanded by cascading

• Industrial temperature range available (–40°C to +85°C) for 74F280B
