SN74S280N

Overview

The SN74S280N is a 9-bit odd/even parity generator/checker from the Texas Instruments S Series. It operates with a supply voltage range of 4.75 V to 5.25 V and accepts inputs from I0 through I8. The device provides complementary outputs labeled Odd and Even. It utilizes Schottky TTL logic technology and is housed in a standard 14-pin plastic dual in-line package (PDIP).

Feature Summary

• Provides simultaneous generation and checking of odd and even parity for nine data bits.
• Features complementary Odd and Even outputs for flexible logic interfacing.
• Utilizes Schottky TTL technology for high-speed switching performance.

Applications

• Data transmission systems requiring error detection via parity verification.
• Memory modules utilizing parity bit generation for data integrity checks.
• Digital communication interfaces implementing odd or even parity protocols.

Procurement Notes

Verify that the component matches the specific S Series designation and PDIP-14 package configuration. Confirm the manufacturer identification aligns with Texas Instruments production standards. Ensure the part number suffix corresponds to the required commercial temperature range specifications before finalizing procurement orders.

Selection Notes

Select this component when a dedicated nine-bit parity solution within the S Series family is required. Consider the complementary output structure if both odd and even states must be monitored simultaneously. Evaluate the Schottky TTL input compatibility against existing system logic levels to ensure proper signal interfacing without additional buffering.

Part Context

This device belongs to the SN54/74S280 family, which includes LS variants offering lower power consumption. The S Series designation indicates the use of Schottky clamping diodes to prevent saturation and improve switching speeds compared to standard TTL counterparts. It serves as a specialized logic function within broader digital processing architectures.
