74LVC244AE4Q

Overview

The IDT 74LVC244AE4Q is a 3.3V CMOS octal buffer and driver belonging to the 74LVC series, manufactured by Integrated Device Technology Inc. It features eight independent buffer/driver channels with three-state outputs, designed for high-density memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device operates within standard industrial temperature ranges and supports mixed-mode voltage operation. Moisture Sensitivity Level (MSL) is rated at 3 (168 hours under JESD-020 conditions).

Feature Summary

• Octal configuration providing eight independent buffer or driver channels.
• Three-state output capability allowing direct connection to bus structures.
• CMOS technology optimized for low power consumption and high-speed performance.
• Supports mixed-mode voltage operation for interfacing diverse logic families.

Applications

• Memory address drivers in computer systems.
• Clock distribution networks requiring buffering.
• Bus-oriented receiver and transmitter circuits.
• High-density digital signal routing applications.

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS status as 'Not Applicable' per available documentation. Check MSL rating of 3 for proper storage and handling requirements. Ensure package type matches design specifications before ordering.

Selection Notes

Select this part when an octal buffer with three-state outputs is required for 3.3V CMOS logic systems. Consider the 74LVC series characteristics for low voltage operation. Verify pin compatibility and package dimensions against existing board layouts. Evaluate thermal performance if operating near maximum temperature limits.

Part Context

This component is part of the broader 74LVC family of logic devices, which are widely used in consumer electronics and computing. IDT, now part of Renesas Electronics, produced this line before integration. The 74LVC244 variant specifically addresses the need for multiple buffered outputs in compact packages, serving as a standard solution for bus isolation and signal conditioning in modern digital designs.

Replacement Considerations

Compatible substitutes include other octal buffers from the 74LVC family, such as the SN74LVC244A from Texas Instruments. Ensure functional equivalence regarding voltage levels, output drive strength, and package footprint. Verify that alternative parts meet the same moisture sensitivity and operating temperature requirements.
