Overview
The SNJ54HCT541J is a military-grade octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to 125°C. The device utilizes a 20-pin ceramic dual in-line package (CDIP). Key electrical characteristics include high-current outputs capable of driving up to 15 LSTTL loads, with output drive currents of ±6 mA at 5 V. Typical propagation delay is 12 ns, and maximum input current is 1 µA.
Feature Summary
- Features inputs and outputs on opposite sides of the package to facilitate printed circuit board layout.
- Provides high-current three-state outputs that interface directly with system buses.
- Includes dual output enable controls for flexible bus management.
Applications
- Military and defense electronic systems requiring extended temperature operation.
- High-performance bus buffering applications.
- Line driving interfaces for digital logic circuits.
Procurement Notes
Verify the specific ordering suffix 'J' corresponds to the CDIP package and QML certification status required for your application. Confirm RoHS compliance details, as military variants may differ from standard catalog parts. Ensure the supplier provides traceability documentation consistent with military procurement standards.
Selection Notes
Select this component when military-grade reliability and wide temperature tolerance are mandatory. The HCT series ensures TTL voltage compatibility while maintaining CMOS low power consumption. Consider the physical dimensions of the 20-lead CDIP package during mechanical design to ensure adequate clearance on the printed circuit board.
Part Context
This part belongs to the SN54HCT541 family, which includes commercial (SN74) and military (SN54/SNJ) versions. The SNJ prefix indicates a specific military qualification level. Other packages in the family include SOIC, SSOP, and LCCC, offering flexibility for different manufacturing processes while maintaining identical logical functionality.
Replacement Considerations
Direct substitutes include other SN54HCT541 variants with different package options such as SN54HCT541J or SNJ54HCT541FK. Verify pinout compatibility and thermal resistance differences if switching between package types like CDIP and LCCC.
