SN74ACT7814-25DL

FIFOs Memory Overview

The SN74ACT7814-25DL 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 contains two independent circuits within a single package. It operates on a unidirectional bus and requires a power supply voltage between 4.5 V and 5.5 V. The maximum power supply current is 400 uA. The device supports operation within a temperature range of 0°C to +70°C and is housed in a 56-pin SSOP package.

FIFOs Memory Feature Summary

FIFOs Memory Procurement Notes

Verify the specific suffix '25' against the official Texas Instruments datasheet to confirm performance grades or package variations. Ensure compatibility with 5V logic levels and check for RoHS compliance status. Confirm availability through authorized distributors as lead times may vary. Validate pinout configurations against the SSOP-56 footprint requirements for your PCB design.

FIFOs Memory Selection Notes

Select this component when asynchronous data transfer with an 18-bit word width is required. The dual-circuit feature allows for efficient space utilization in designs needing multiple independent buffers. Verify that the 4.5V to 5.5V operating voltage aligns with your system's power rails. Consider the SSOP-56 package size constraints during layout planning.
