The 74LS280 IC is a versatile component designed for odd/even parity generation and checking. It can be easily cascaded to expand word length and operates at a wide range of working conditions. The IC interfaces directly with CMOS, NMOS, and TTL, providing TTL output for seamless integration with other devices and microcontrollers.
The IC is designed without the expander input implementation, allowing it to be substituted for the LS180 with improved performance. It features buffered inputs to lower drive requirements to one LS unit load, enhancing its efficiency.
A parity generator is a combinational logic circuit used to generate the parity bit in the transmitter, while a parity checker verifies the parity in the receiver. These circuits are essential in digital systems to detect single-bit errors in transmitted data words, ensuring data integrity.
Applications:
- Used to detect errors in transmitted data caused by noise or other disturbances
Package Includes:
- 1 X 74LS280 IC - (SMD Package) 9-Bit Odd-Even Parity Generator Checker IC (74280 IC)
