Key Features
- 9-bit odd/even parity generator and checker enables simultaneous parity generation and verification in a single device
- Advanced CMOS (AC) technology provides high-speed switching with low power consumption and CMOS-compatible inputs
- High output sink current of 75mA supports driving multiple loads and bus lines in demanding digital systems
- Dual parity output (odd and even) eliminates the need for external inversion logic in mixed parity systems
Applications
The CD74AC280M is widely used in memory systems, data storage controllers, and communication interfaces where data integrity verification is critical. It generates and checks parity bits for 8-bit data buses, providing error detection in DRAM, SRAM, and EEPROM memory interfaces. The device also finds application in industrial control systems and network equipment where reliable data transmission and bit-error detection are required.

Frequently Asked Questions
What parity modes does the CD74AC280M support?
The CD74AC280M supports both odd and even parity generation and checking simultaneously, with separate outputs for each parity type, allowing flexible integration into systems requiring either parity convention without additional inverter logic.
What is the maximum output current of the CD74AC280M?
The CD74AC280M provides a maximum output low current (I_OL) of 75mA, enabling it to sink significant current for driving multiple logic inputs, bus transceivers, or resistive loads in high-fanout applications.
What package does the CD74AC280M use?
The CD74AC280M is available in a 14-pin SOIC package (JESD-30 code R-PDSO-G14), a standard surface-mount package that is widely supported by automated PCB assembly equipment and offers good thermal performance.
How many bits can the CD74AC280M check?
The CD74AC280M is a 9-bit parity generator and checker, capable of processing 9 data inputs simultaneously. This makes it ideal for checking parity on standard 8-bit data bytes with one additional parity bit input.
Is the CD74AC280M compatible with TTL and CMOS logic families?
Yes, the CD74AC280M belongs to the AC Advanced CMOS family and is compatible with TTL input levels, allowing direct interfacing with both TTL and CMOS logic devices without the need for level-shifting circuitry.
