74HC40105D,653

FIFOs Memory Overview

The Nexperia 74HC40105D,653 is a first-in/first-out (FIFO) elastic storage register housed in a 16-lead SO plastic small outline package (SOT109-1). It stores sixteen 4-bit words and supports independent asynchronous inputs and outputs. The device operates with a supply voltage range of 2.0 V to 6.0 V and functions across an ambient temperature range of -40 °C to +125 °C. It features three-state outputs, CMOS input levels, and status indicators for data readiness.

FIFOs Memory Feature Summary

• Provides elastic buffering between asynchronous systems by handling input and output data at different shifting rates.
• Includes dedicated status flag outputs to indicate when the FIFO is ready for new data or contains valid data.
• Supports expansion in either direction to increase word length or capacity without requiring external components.

FIFOs Memory Applications

• Buffering data between asynchronous systems
• High-speed burst mode data transfer applications
• Expanding FIFO word length through cascading

FIFOs Memory Procurement Notes

Verify that the component matches the specified 16-lead SO package and temperature rating. Confirm the ordering suffix aligns with the required tape and reel packaging format. Ensure the revision level corresponds to the latest product data sheet version to guarantee accurate electrical characteristics and pin configuration.

FIFOs Memory Selection Notes

Select this component when a compact FIFO solution is needed for buffering asynchronous data streams. It is suitable for designs requiring status flags to manage data flow efficiently. Consider its operating voltage range and temperature specifications to ensure compatibility with the target system environment and interface requirements.
