Overview
The SNJ54AHC126J is a quadruple bus buffer gate manufactured by Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 2 V to 5.5 V and supports unidirectional data flow. The device utilizes the AHC logic series for high-speed performance. It is housed in a 14-pin ceramic dual in-line package (CDIP) designed for military-grade reliability. The component functions as a non-inverting buffer with an active-low enable control mechanism.
Feature Summary
- Provides four independent non-inverting buffer channels with three-state output capability
- Operates across a wide supply voltage range from 2 V to 5.5 V
- Features low input capacitance to minimize driver loading effects
- Designed for military specifications with extended temperature range support
Applications
- Military avionics signal buffering
- High-reliability data bus isolation
- Spacecraft communication interface circuits
- Harsh environment digital logic translation
Procurement Notes
Verify the specific suffix J indicates the ceramic DIP package and military grade qualification. Confirm RoHS compliance status as military parts may differ from commercial standards. Check datasheet revision history for any pinout or electrical parameter updates. Ensure the supplier provides traceability documentation required for defense contracts.
Selection Notes
Select this component when military-grade environmental resilience is mandatory. Compare propagation delay specifications against system timing requirements. Evaluate power consumption at the target operating voltage. Consider the physical size constraints of the CDIP package relative to the PCB layout.
Part Context
This part belongs to the SN54/74AHC126 family of quadruple bus buffers. It shares functional compatibility with commercial variants but differs in packaging and qualification standards. The SNJ prefix denotes the military version produced under strict quality controls. It serves as a critical interface element in systems requiring high noise immunity.
Replacement Considerations
SNJ54AHCT126J offers compatible functionality with CMOS-compatible inputs.
