Overview
The SN54ALS832AJ is a military-grade hex two-input OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features ultra-high-speed performance with a propagation delay of 4 ns. The device utilizes bipolar technology and is housed in a 20-pin CDIP package. It supports an operating temperature range from -55°C to 125°C, ensuring reliability in harsh environments.
Feature Summary
- Military-grade construction for extreme environmental reliability
- Ultra-high-speed logic operation with 4 ns propagation delay
- Hex configuration providing six independent two-input OR gates
Applications
- Military avionics logic systems
- Spacecraft data processing units
- High-reliability industrial control interfaces
Procurement Notes
Verify the specific suffix 'J' confirms the 20-pin CDIP package and military temperature rating. Confirm the manufacturer is Texas Instruments or an authorized source. Check for RoHS compliance status as older military parts may not meet current standards. Ensure the component is new old stock or properly qualified if sourcing from third-party distributors.
Selection Notes
Select this component when high-speed OR logic is required in military or aerospace applications. The ALS series offers a balance of speed and power consumption suitable for complex digital systems. Ensure the design accommodates the 20-lead ceramic DIP footprint and thermal requirements for the -55°C to 125°C operating range.
Part Context
This part belongs to the SN54ALS family of high-speed Schottky TTL logic devices. The SN54 series denotes military qualification, distinguishing it from the commercial SN74 variants. It provides robust signal integrity and noise immunity for critical digital circuits requiring fast switching speeds in demanding operational conditions.
Replacement Considerations
Direct substitutes include other military-grade hex OR gates such as the SN54LS832A, though with slower performance. Verify pin compatibility and electrical specifications before substitution. Cross-reference with SN54AS832A for faster alternatives if available.
