SN74ACT7814-20DLR

FIFOs Memory Overview

The SN74ACT7814-20DLR is an asynchronous FIFO memory device manufactured by Texas Instruments. It features a data bus width of 18 bits and a storage capacity of 1.125 kbit, organized as 64 words by 18 bits. The component operates within a supply voltage range of 4.5 V to 5.5 V with a maximum power supply current of 400 uA. It supports two independent circuits and functions in unidirectional mode. The device is designed for surface mount installation in an SSOP-56 package and operates at temperatures between 0°C and +70°C.

FIFOs Memory Feature Summary

• Asynchronous operation for flexible timing integration
• Dual circuit configuration within a single package
• Wide 18-bit data bus capability

FIFOs Memory Applications

• Data buffering in high-speed digital systems
• Level shifting between different logic families
• Temporary data storage in communication interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix 'DLR' against official Texas Instruments documentation to confirm tape-and-reel packaging and exact electrical grade. Ensure compatibility with standard 5V logic levels and check for any lead-free or RoHS compliance requirements relevant to your manufacturing process before finalizing procurement orders.

FIFOs Memory Selection Notes

Select this component when an asynchronous interface is required for 18-bit data paths. The dual-circuit design allows for efficient space utilization compared to single-circuit alternatives. Verify that the 64-word depth meets system latency requirements and that the SSOP-56 footprint aligns with PCB layout constraints.

FIFOs Memory Part Context

This part belongs to the SN74ACT7814 series of asynchronous FIFO memories. It shares functional similarities with other members like the SN74ACT7813 but differs in access speed and synchronization type. The ACT series provides CMOS performance with TTL-compatible inputs, bridging legacy and modern logic standards.

FIFOs Memory Replacement Considerations

Check for direct pin-to-pin replacements such as the SN74ACT7814-20DL if reel packaging is not strictly required. Verify that substitute parts maintain the same 18-bit width and asynchronous timing characteristics to ensure circuit functionality remains unchanged.
