Overview
The 54HC30/BCA is a high-speed CMOS logic component manufactured by Rochester Electronics, LLC. It functions as an eight-input NAND gate within the HC/UH series. The device utilizes a ceramic dual in-line package (CDIP) with 14 terminals and glass-sealed construction. It operates asynchronously with negative edge triggering for associated counter functions in the broader family context, though this specific part is a gate. The operational temperature range spans from -55 °C to 125 °C. It supports load/preset inputs and is designed for up-direction counting applications in compatible system architectures.
Feature Summary
- High-speed CMOS technology implementation
- Ceramic dual in-line package with glass sealing
- Extended industrial temperature operation capability
- Asynchronous logic processing functionality
Applications
- Digital signal processing circuits
- Logic operations in electronic control systems
- Binary counting applications requiring asynchronous input
- Military or aerospace qualified logic systems
Procurement Notes
Verify the specific ordering suffix and package variant against the required mechanical specifications. Confirm that the lead time and availability align with project schedules, as Rochester Electronics manages legacy production. Ensure compliance with RoHS and lead-free status requirements for the intended assembly process. Cross-reference the manufacturer's documentation for any changes in qualification standards or testing procedures.
Selection Notes
Select this component when a robust, high-speed NAND gate is required for harsh environments. The ceramic package provides superior durability compared to plastic alternatives. Consider the extended temperature range for applications exceeding standard commercial limits. Verify pin compatibility with existing PCB footprints before integration into the design.
Part Context
Rochester Electronics specializes in sustaining obsolete semiconductor technologies. This part belongs to the 54HC/UH series, ensuring continuity for designs relying on established logic families. The company maintains licensed production of these devices to support long-term manufacturing needs where original manufacturers have discontinued supply.
Replacement Considerations
Direct substitutes include other 54HC30 variants from different manufacturers offering identical logical function and pinout. Verify package dimensions and thermal characteristics when considering alternative sources. Ensure voltage levels and noise immunity match the system requirements.
