Description

The 74HCT7080 is high-speed Si-gate CMOS devices. They are specified in compliance with JEDEC standard no. 7A.

The 74HCT7080 is 16-bit parity generators or checkers commonly used to detect errors in high-speed data transmission or data retrieval systems.

The even and odd parity output of the 74HCT7080 is available for generating or checking even/odd parity up to 16-bits.

The even/odd parity output (E/,O) of the 74HCT7080 is HIGH when an even number of data inputs (I0 to I15) are HIGH and the cascade/even-odd-changing input (,X) is HIGH.


Expansion to larger word sizes is accomplished by connecting the even/odd parity output (E/,O) to the cascade/even-odd-changing input (,X) of the final stage.
