8400002EA

Overview

The Texas Instruments part number 8400002EA corresponds to the SN54ALS112A, a dual J-K negative-edge-triggered flip-flop. This component is housed in a 16-pin Ceramic Dual In-Line Package (CDIP) designated as package J. It is engineered for military-grade reliability with an extended operating temperature range spanning from -55°C to +125°C. The device integrates dedicated Clear and Preset inputs to allow direct control over the output states independent of the clock signal.

Feature Summary

Dual channel configuration providing two independent J-K flip-flops within a single integrated circuit
Negative-edge triggering mechanism synchronized with the clock input signal transitions
Integrated asynchronous Clear and Preset functions for immediate state initialization

Applications

Military aerospace systems requiring high-temperature stability
Industrial control logic circuits demanding reliable data storage
High-reliability computing memory registers

Procurement Notes

Verify that the specific order matches the SN54ALS112A designation and CDIP (J) package type. Confirm the military temperature rating (-55°C to +125°C) aligns with system requirements. Ensure the 16-pin ceramic construction is specified for environmental durability. Cross-reference the manufacturer part number to avoid confusion with commercial variants.

Selection Notes

Select this component when dual J-K functionality is required in harsh thermal environments. The SN54 series ensures performance consistency across extreme temperatures compared to standard industrial grades. The CDIP package offers superior mechanical strength and hermetic sealing. Consider the negative-edge trigger timing characteristics for synchronous design compatibility.

Part Context

This device belongs to the SN54ALS family, representing Advanced Low-Power Schottky logic technology. The SN54 series is distinguished by its military qualification and wide temperature range. It provides faster switching speeds than standard TTL while maintaining low power consumption. The dual flip-flop architecture supports complex sequential logic designs.
