Overview
The 54F175/B2A is a high-speed ECL-compatible quad D-type flip-flop manufactured by Rochester Electronics. It features separate clock inputs for each flip-flop and includes both true and complemented outputs. The device is designed for operation over the full military temperature range of -55°C to 125°C, ensuring reliability in harsh environments. It utilizes a ceramic dual in-line package (CDIP) with 16 pins, suitable for high-reliability applications requiring fast switching speeds and robust performance standards.
Feature Summary
- Provides four independent D-type flip-flops with dedicated clock inputs for precise timing control
- Delivers both true and complemented outputs for flexible logic interfacing
- Engineered for full military temperature range operation from -55°C to 125°C
- Constructed in a hermetically sealed ceramic package for enhanced environmental durability
Applications
- Military aerospace data processing systems
- High-speed digital signal processing circuits
- Radar and communication equipment timing registers
- Space-qualified computer memory modules
Procurement Notes
Verify the specific suffix B2A against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the component meets MIL-PRF-38535 Class Q or V requirements if specified for your application. Confirm that the ceramic package integrity is intact upon receipt to maintain hermetic sealing standards required for military and space-grade deployments.
Selection Notes
Select this component when designing systems that require ECL-compatible logic levels and high-speed switching capabilities within a military temperature envelope. The availability of both true and complemented outputs simplifies circuit design by eliminating external inverters. Consider the ceramic packaging for superior thermal conductivity and radiation hardness compared to plastic alternatives in extreme operational conditions.
Part Context
This part belongs to the SN54F175 family of high-speed ECL-compatible quad D-type flip-flops. Rochester Electronics manufactures these components using original die or recreated wafers approved by the Original Component Manufacturer. They are tested to meet or exceed original datasheet specifications, ensuring consistency with legacy military and aerospace electronic systems that rely on proven F-series logic technologies.
Replacement Considerations
Direct replacements include other SN54F175 variants from qualified manufacturers such as Texas Instruments or Analog Devices, provided they match the CDIP-16 package and military temperature rating. Verify that any substitute maintains ECL voltage levels and pin compatibility. Cross-reference with MIL-PRF-38535 qualified lists to ensure equivalent reliability standards are met for critical mission applications.
