Overview
INTEGRATED CIRCUITS 74F280B 9-bit odd/even parity generator/checker Product specification IC15 Data Handbook 1996 Mar 12 Philips Semiconductors Philips Semiconductors Product specification 9-bit odd/even parity generator/checker 74F280B FEATURES • High-impedance NPN base inputs for reduced loading (20µA in Low and High states) PIN CONFIGURATION I6 I7 NC I8 ΣE ΣO GND 1 2 3 4 5 6 7 14 VCC 13 I5 12 I4 11 I3 • Buffered inputs — one normalized load • Word length easily expanded by cascading • Industrial temperature range available (–40°C to +85°C) DESCRIPTION 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 when an even number of Data inputs (I0 - I8) are High.
The Odd (∑O) parity output is High when an odd number of Data inputs are High...
