Overview
The SN54ALS30AJ is a military-grade, high-speed ALS series logic component manufactured by Texas Instruments. It functions as an 8-input positive-NAND gate housed in a 14-pin ceramic dual in-line package (CDIP). The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended temperature range from -55°C to 125°C. Key electrical characteristics include a maximum propagation delay of 19 ns and a maximum power supply current of 0.6 mA.
Feature Summary
- Provides one 8-input NAND logic function for complex signal processing
- Utilizes low-power Schottky (ALS) technology for enhanced speed and efficiency
- Features hermetically sealed ceramic packaging suitable for harsh environments
Applications
- Military avionics systems requiring radiation-hardened or high-reliability logic
- Spacecraft guidance and control circuitry operating under extreme thermal conditions
- High-speed data processing gates in defense communication equipment
Procurement Notes
Verify the specific suffix 'AJ' corresponds to the intended ceramic package variant and lead-free status if required. Confirm that the military rating aligns with project specifications. Ensure compatibility with existing 5V logic levels. Check for any specific handling requirements associated with ceramic packages. Validate that the manufacturer source is authorized.
Selection Notes
Select this component when an 8-input NAND function is required in space-constrained military applications. The ALS family offers a balance between speed and power consumption compared to standard TTL. The CDIP package provides superior environmental protection compared to plastic variants. Consider pinout compatibility with existing designs utilizing the SN54LS30 or SN54S30 families.
Part Context
This part belongs to the Texas Instruments SN54 series, which denotes military-grade performance and reliability standards. The ALS designation indicates the use of Advanced Low-power Schottky technology, offering faster switching speeds than LS series devices while maintaining lower power dissipation. The 30 series specifically defines the 8-input NAND gate configuration within this logic family.
Replacement Considerations
Direct functional substitutes include the SN54LS30 and SN54S30, though these differ in speed and power characteristics. Verify pin compatibility before substitution. Other ALS series components may require level shifting or timing adjustments.
