54AC00/SDA-R

Overview

The 54AC00/SDA-R is a high-speed CMOS quad 2-input NAND gate manufactured by Rochester Electronics. It operates within a supply voltage range of 4.5 V to 5.5 V and features propagation delays of approximately 14 ns. The device is housed in a hermetic ceramic DIP-14 package, designed for military and aerospace applications requiring radiation hardness against total ionizing dose, single event latch-up, and single event upset.

Feature Summary

• High-speed CMOS logic technology optimized for demanding environments
• Hermetically sealed ceramic packaging ensuring environmental protection
• Radiation hardened design suitable for space and harsh conditions

Applications

• Military avionics systems
• Spacecraft digital logic circuits
• Harsh environment data processing

Procurement Notes

Verify the specific suffix 'SDA' against official manufacturer documentation to confirm exact pinout, lead finish, and qualification level. Ensure the component meets required radiation hardness specifications for the intended application environment before procurement.

Selection Notes

Select this component when radiation tolerance and hermetic sealing are mandatory. Compare propagation delay and power consumption against other AC series variants to ensure compatibility with system timing requirements and thermal constraints.

Part Context

Rochester Electronics specializes in lifecycle management for obsolete and hard-to-find semiconductors. This part belongs to the 54AC series, which provides high-speed performance compatible with standard TTL logic levels while offering improved noise immunity and lower power consumption compared to older technologies.

Replacement Considerations

Direct replacements must match the 54AC00 function, DIP-14 hermetic package, and radiation hardness ratings. Verify equivalent parts from manufacturers like Texas Instruments or Microchip that offer QML-V or MIL-PRF-38534 qualifications.
