CD74HC7030E

FIFOs Memory Overview

The CD74HC7030E is a high-speed CMOS asynchronous/synchronous FIFO memory device manufactured by Harris Corporation. It features a 64-word by 9-bit configuration with uni-directional data flow and operates at frequencies up to 33MHz. The component is housed in a 28-pin Plastic Dual In-line Package (PDIP). It supports a supply voltage range typical for HC series logic, ensuring compatibility with standard digital systems requiring reliable temporary data storage.

FIFOs Memory Feature Summary

• Supports both asynchronous and synchronous operation modes for flexible system integration
• Provides 64-word by 9-bit capacity for efficient data buffering
• Uni-directional data transfer architecture simplifies interface design
• Operates at clock frequencies up to 33MHz for high-speed applications

FIFOs Memory Applications

• Data buffering in serial-to-parallel conversion circuits
• Interface bridging between microprocessors and peripheral devices
• Temporary storage in communication protocol handlers
• Synchronization buffers in digital signal processing chains

FIFOs Memory Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successors, noting that original Harris logic products may now be distributed under different corporate entities such as Intersil or Renesas. Confirm the package type is 28-PDIP and check for any specific suffix variations that might indicate temperature grade or lead-free compliance. Ensure datasheets match the HC series electrical characteristics rather than HCT or other variants.

FIFOs Memory Selection Notes

Select this component when a 9-bit wide FIFO buffer is required within a 28-pin DIP footprint. The HC series technology offers standard CMOS input/output levels suitable for 5V logic systems. Consider the 33MHz maximum frequency against your system clock requirements. Verify that the uni-directional nature meets your data flow needs, as bidirectional alternatives exist in other part numbers.

FIFOs Memory Part Context

This device belongs to the CD74HC family of high-speed CMOS logic components originally developed by Harris Corporation. The HC series is characterized by wide operating voltage ranges and low power consumption compared to older TTL technologies. This specific FIFO variant addresses memory buffering needs within the broader logic IC portfolio, complementing gates, flip-flops, and shift registers offered by the same manufacturer.

FIFOs Memory Replacement Considerations

Check for equivalents from Intersil or Renesas, which acquired Harris's semiconductor assets. Verify pin compatibility and electrical specifications against modern FIFO replacements like those from Texas Instruments or ON Semiconductor. Ensure the replacement maintains the 28-pin DIP package if board space constraints are critical.
