CD74HCT40105MT

FIFOs Memory Overview

The CD74HCT40105MT is a high-speed CMOS logic asynchronous FIFO register manufactured by Texas Instruments. It features a 4-bit by 16-word memory depth, providing 64 bits of storage capacity in a unidirectional configuration. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes a 16-pin SOIC surface-mount package. Key electrical specifications include a maximum clock frequency of 32MHz and a propagation delay of 265ns. It supports low-level output currents of 4mA and high-level output currents of -4mA, with an operating temperature range from -55°C to +125°C.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible data buffering.

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices
• Level shifting between different voltage domains
• Synchronization of data streams in digital systems

FIFOs Memory Procurement Notes

Verify the specific suffix 'MT' indicates the tape-and-reel packaging format and SOIC-16 package variant. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the required package type and reel quantity specifications before finalizing procurement.

FIFOs Memory Selection Notes

Select this component when an asynchronous FIFO interface is required for 4-bit wide data paths. The HCT series compatibility ensures direct interfacing with standard TTL logic levels. Consider the 16-word depth for moderate buffering needs and the wide operating temperature range for industrial applications.

FIFOs Memory Part Context

This component belongs to the Texas Instruments 74HCT logic family, designed for high-speed CMOS operation with TTL-compatible inputs. The CD74HCT40105 series provides dedicated FIFO functionality, distinguishing it from general-purpose shift registers or static RAMs by integrating control logic for full/empty status flags directly on-chip.

FIFOs Memory Replacement Considerations

Cross-reference with other 74HCT40105 variants such as the CD74HCT40105E (PDIP package) if through-hole mounting is required. Verify pinout compatibility and electrical characteristics against alternative manufacturers' asynchronous FIFO ICs offering similar 4x16 configurations.
