Overview
The SN54S134J is a military-grade, high-speed bipolar logic device manufactured by Texas Instruments. It functions as a single 12-input positive-NAND gate featuring 3-state outputs. The component operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 16-pin Ceramic Dual In-Line Package (CDIP). It supports an extended industrial temperature range from -55°C to +125°C, ensuring reliability in demanding environments.
Feature Summary
- Provides a single 12-input positive-NAND logic function with 3-state output capability for bus-oriented applications.
- Constructed using high-speed bipolar technology for rapid signal processing.
- Designed for military specifications with robust performance across extreme temperature variations.
Applications
- Military aerospace digital systems
- High-reliability communication equipment
- Industrial control logic interfaces
Procurement Notes
Verify the specific suffix 'J' confirms the ceramic dual in-line package and military grade status. Confirm the active production status directly with Texas Instruments or authorized distributors. Ensure compatibility with existing 5V bipolar logic families. Check for any specific handling requirements associated with ceramic packages.
Selection Notes
Select this component when a single 12-input NAND gate is required in a military environment. It is suitable for designs needing 3-state outputs on a shared bus. Consider the CDIP package constraints for PCB layout. Verify that the 12-input requirement cannot be met by cascading smaller gates more efficiently.
Part Context
This part belongs to the Texas Instruments SN54S series of high-speed bipolar logic devices. The SN54 prefix indicates military qualification, distinguishing it from commercial SN74 equivalents. The S series denotes high-speed performance characteristics typical of bipolar transistor-transistor logic technologies.
Replacement Considerations
Direct replacements include other military-grade 12-input NAND gates with 3-state outputs from compatible manufacturers. Verify pinout compatibility before substitution. Cross-reference with SN54LS134 variants if lower power consumption is acceptable, noting the speed difference.
