JD54F158BFA

Overview

The JD54F158BFA is a quad 2-input multiplexer from the F/FAST series, manufactured by National Semiconductor. It features four independent 2-to-1 multiplexers with inverted outputs in a single package. The device utilizes a ceramic DFP-16 package with metal-sealed cofired construction. It operates within a temperature range of -55 °C to 125 °C and supports a load capacitance of 50 pF.

Feature Summary

• Contains four independent 2-to-1 multiplexing channels
• Provides inverted output signals for each channel
• Constructed with a metal-sealed ceramic package for durability
• Designed for high-speed logic applications

Applications

• Data routing in military-grade electronic systems
• Signal selection in aerospace instrumentation
• High-reliability industrial control logic circuits

Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets are now managed by Texas Instruments. Confirm the specific suffix 'BFA' corresponds to the ceramic DFP-16 package and military temperature rating. Ensure compatibility with existing system voltage levels and signal integrity requirements before procurement.

Selection Notes

Select this component when a quad multiplexer with inverted outputs is required in a ruggedized environment. The ceramic package offers superior thermal and mechanical stability compared to plastic variants. Consider the 54F series speed characteristics and the specific 16-pin dual flat pack form factor for board layout constraints.

Part Context

This part belongs to the 54F family of high-speed Schottky TTL logic devices. The 54F series is characterized by its robust performance in harsh environments, distinguishing it from commercial 74F counterparts. The JD prefix typically denotes a specific vendor or military-grade variant within the broader 54F multiplexer lineage.

Replacement Considerations

The N54F158A/BFA from NXP is a documented equivalent offering identical functional specifications and pinout. Verify that the substitute maintains the same ceramic packaging and military temperature range if environmental resilience is critical.
