Overview
The SN72258N is a military-grade quadruple 2-line to 1-line data selector/multiplexer featuring 3-state outputs, manufactured by Texas Instruments. It belongs to the SN54/74S series of Schottky TTL logic devices. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports a junction temperature range from -55°C to +125°C. It utilizes a 16-pin CDIP (Ceramic Dual In-Line Package) suitable for high-reliability applications. Key electrical characteristics include a propagation delay of 9 ns and an output current capability of 32 mA per line.
Feature Summary
- Military-grade reliability with extended temperature range capabilities
- Quadruple configuration providing four independent multiplexing channels
- Schottky TTL technology ensuring high-speed switching performance
- Three-state outputs allowing direct bus connection without external buffers
Applications
- Military aerospace avionics systems requiring radiation-hardened or high-reliability logic
- Spacecraft communication subsystems operating in extreme thermal environments
- High-speed digital signal routing in defense-grade computing hardware
- Test and measurement equipment designed for harsh environmental conditions
Procurement Notes
Verify that the specific part number SN72258N corresponds to the military grade variant, distinct from commercial SN74258N units. Confirm package integrity for ceramic dual in-line construction. Ensure compliance with relevant military specifications such as MIL-PRF-38534 if applicable. Request full traceability documentation including lot codes and material certifications. Validate that the device meets the required junction temperature ratings for your specific operational environment before integration.
Selection Notes
Select this component when military-grade reliability and wide temperature operation are mandatory. Compare against SN74258N for commercial alternatives if environmental constraints are less severe. Consider power consumption differences between Schottky and Low-Power Schottky variants. Evaluate pin compatibility with existing PCB footprints designed for 16-pin DIP packages. Assess system timing requirements against the 9 ns propagation delay specification.
Part Context
This device is part of the SN54/74S family, known for Schottky diode clamping to prevent saturation and improve switching speed. It serves as a high-performance alternative to standard TTL logic in demanding applications. The SN72 prefix denotes military qualification, distinguishing it from the commercial SN74 series. It provides robust signal selection capabilities in complex digital architectures.
Replacement Considerations
SN74258N: Commercial grade equivalent with limited temperature range (-55°C to +125°C junction, but typically lower ambient limits). SN54258J: Military grade ceramic J-package variant. Verify pinout compatibility and electrical parameters before substitution.
