SN74ACT7205L50NP

FIFOs Memory Overview

The SN74ACT7205L-50NP is an asynchronous first-in, first-out (FIFO) memory device manufactured by Texas Instruments. It features a memory organization of 8K words by 9 bits, providing a total memory density of 73,728 bits. The component operates with a maximum access time of 50 nanoseconds and a cycle time of 65 nanoseconds. It utilizes a 28-pin plastic dual in-line package (PDIP). The device supports asynchronous operation and includes three-state outputs for bus interfacing compatibility.

FIFOs Memory Feature Summary

• Asynchronous FIFO architecture enabling independent read and write clock domains
• Three-state output capability for direct system bus integration
• High-density storage configuration supporting 8K x 9 bit data width

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• Temporary data storage in high-speed digital signal processing chains

FIFOs Memory Procurement Notes

Verify the specific suffix designation to confirm the exact speed grade and package variant, as variations exist within the ACT series. Confirm lead-free status requirements against project specifications, noting that some variants may not be RoHS compliant. Ensure the PDIP-28 package footprint matches the target PCB layout constraints before finalizing procurement orders.

FIFOs Memory Selection Notes

Select this component when an asynchronous interface is required between logic blocks with mismatched timing characteristics. The 9-bit word width accommodates standard byte-oriented data plus parity or control bits. Verify that the 50ns access time meets the system's throughput requirements and that the 3-state outputs align with the destination bus impedance and drive capabilities.

FIFOs Memory Part Context

This part belongs to the Texas Instruments SN74ACT logic family, which combines the high-speed performance of AC logic with TTL-compatible input thresholds. The ACT series is designed for applications requiring faster switching speeds than standard ALS logic while maintaining compatibility with existing TTL-driven systems. The FIFO variant specifically addresses data flow management needs in complex digital architectures.

FIFOs Memory Replacement Considerations

Direct pin-to-pin replacements within the same family include other SN74ACT7205 variants with different speed grades or packaging options. Cross-family substitution requires careful evaluation of voltage levels and propagation delays. Verify that any alternative maintains the 8Kx9 organization and asynchronous control logic functionality.
