Overview
The DM54LS125AJ/883 is a quad bus driver from the LS-TTL series manufactured by National Semiconductor. It features four non-inverting buffers with three-state outputs, housed in a 14-pin ceramic dual in-line package (CDIP). The device operates at a nominal supply voltage of 5 V and supports a maximum operating frequency of 30 MHz. It is designed for military-grade environments, functioning within a temperature range of -55 °C to 125 °C.
Feature Summary
- Provides four independent non-inverting buffer channels
- Features three-state output capability for bus line isolation
- Constructed in a hermetic ceramic DIP package for environmental durability
Applications
- Military-grade digital logic systems
- Bus-oriented memory and data transmission architectures
- High-reliability industrial control circuits
Procurement Notes
Verify that the component carries the MIL-STD-883 Class C screening level certification required for military applications. Confirm the presence of the 'J' suffix indicating a ceramic package and the '/883' designation for standardized testing. Ensure the manufacturer is identified as National Semiconductor or its successor Texas Instruments to guarantee authenticity and traceability.
Selection Notes
Select this component when a high-speed, low-power TTL buffer with tri-state functionality is required for critical systems. It is suitable for designs needing robust thermal performance across extreme temperatures. Consider the ceramic package for superior sealing compared to plastic alternatives in harsh environments.
Part Context
This part belongs to the DM54LS family, which denotes military-grade Low-power Schottky TTL logic. The /883 suffix indicates compliance with MIL-STD-883 standards. It serves as a specialized variant of standard commercial LS125 drivers, offering enhanced reliability and radiation hardness characteristics for defense and aerospace sectors.
Replacement Considerations
Direct substitutes include other military-grade LS125 variants such as the DM54LS125J/883. Verify pin compatibility and electrical specifications before replacing.
