What are the key features of SN74ALS280N?
- 9-bit odd/even parity generator and checker with complementary outputs enabling simultaneous generation of both parity polarities in error detection circuits
- 3-state output capability allowing multiple devices to share a common bus line, simplifying data integrity verification in bus-based system architectures
- ALS (Advanced Low-power Schottky) logic family in a 14-pin DIP package offering a balance of high speed and low power for legacy and new digital designs
What is SN74ALS280N used for?
The SN74ALS280N is used in data communication and memory systems to generate and verify parity bits for single-bit error detection in parallel data buses. It is commonly found in DRAM memory controllers, UART interfaces, and data transmission equipment where data integrity must be confirmed at each transfer. Its complementary outputs and 3-state capability make it easy to integrate into existing bus architectures without additional glue logic.

Frequently Asked Questions
What is the primary function of the SN74ALS280N?
The SN74ALS280N is a 9-bit parity generator and checker that can produce both odd and even parity outputs simultaneously. It is used in digital systems to detect single-bit errors in parallel data words during transmission or storage.
Does the SN74ALS280N support 3-state outputs?
Yes, the SN74ALS280N features 3-state (tri-state) outputs, which allow the device to be disabled and disconnected from the bus when not active, making it suitable for shared bus architectures in memory and communication systems.
What package does the SN74ALS280N use?
The SN74ALS280N is housed in a 14-pin plastic DIP (Dual In-line Package) through-hole package (JESD-30 code R-PDIP-T14), making it easy to use in prototype breadboards and through-hole PCB designs.
What logic family does the SN74ALS280N belong to?
The SN74ALS280N belongs to the ALS (Advanced Low-power Schottky) TTL logic family, which provides improved speed compared to standard LS TTL while consuming less power, suitable for both legacy system repair and new designs requiring TTL compatibility.
