What is SN74AS286N used for?
The SN74AS286N is used in memory system error detection, data bus integrity checking, and communication protocol parity verification where 9-bit (8 data + 1 parity) error detection is required. Its high output drive current and AS-family speed make it suitable for high-throughput memory controllers, error-correcting code (ECC) circuits, and parallel data link parity checking in industrial computing systems.

Frequently Asked Questions
What parity functions does the SN74AS286N support?
The SN74AS286N supports both even parity generation and odd/even parity checking across 9 data bits. When used as a generator, it produces an even parity bit for 8 data inputs. As a checker, it can detect both odd and even parity errors on a 9-bit word, with an active-low parity error output that goes low when a parity mismatch is detected.
What is the output drive current of the SN74AS286N?
The SN74AS286N provides a maximum output sink current (I(ol)) of 48mA, which is among the highest in standard TTL logic families. The AS (Advanced Schottky) logic family delivers this drive capability with fast switching speed, making the device suitable for driving terminated bus lines and heavily loaded parallel data paths in high-speed computing systems.
What package is the SN74AS286N available in and is it RoHS compliant?
The SN74AS286N is packaged in a 14-pin plastic dual in-line package (PDIP) with JESD-30 code R-PDIP-T14. The JESD-609 code e4 indicates it is a lead-free, RoHS-compliant device. This through-hole package makes it suitable for prototype development, high-reliability through-hole assemblies, and replacement of legacy parity generator/checker circuits.
What is the bus driver parity I/O port feature of the SN74AS286N?
The SN74AS286N includes a parity I/O port that can be used bidirectionally, allowing the device to either generate a parity bit onto the bus or receive and check an incoming parity bit from the bus. This single-device capability eliminates the need for separate parity generator and checker ICs in designs that require both transmit and receive parity operations.
