Overview
The SNJ54LS375J is a military-grade octal transparent latch from Texas Instruments, part of the SN54LS375 family. It features eight D-type latches with common clock and output enable inputs. The device operates within an extended temperature range of -55°C to 125°C. It is housed in a 16-pin Ceramic Dual In-Line Package (CDIP) designed for high-reliability applications. The component utilizes LS TTL logic technology.
Feature Summary
- Military-grade construction certified for defense and aerospace environments
- Octal configuration providing eight independent transparent latches
- Common control inputs for synchronized clocking and output enabling
Applications
- Military and defense electronic systems
- Aerospace data storage circuits
- High-reliability industrial control interfaces
Procurement Notes
Verify the specific ordering suffix J indicates the ceramic dual in-line package variant. Confirm RoHS exemption status as military parts often differ from commercial standards. Ensure the supplier provides traceability documentation required for QML certified components. Validate that the operating temperature range meets the -55°C to 125°C specification for your environment.
Selection Notes
Select this component when military certification and wide temperature operation are mandatory. Compare against SN74LS375 variants if commercial grade suffices. Consider the CDIP package constraints for PCB layout. Verify compatibility with existing LS TTL logic levels and power supply requirements.
Part Context
This part belongs to the SN54LS375 family of octal latches. The SN54 prefix denotes military qualification, distinguishing it from the commercial SN74 series. It serves as a parallel-to-serial interface element or temporary data storage node in digital systems requiring robust performance under extreme conditions.
Replacement Considerations
SN54LS375J.A is a qualified alternative within the same package and specification set. Commercial equivalents like SN74LS375N lack the required temperature range and military certification.
