74LVC244AE4PY

Overview

The 74LVC244AE4PY is an octal buffer and line driver manufactured by IDT, operating at a supply voltage of 3.3V. It belongs to the 74LVC logic family and provides eight output channels per device. The component is classified as a CMOS buffer/driver within the broader category of logic integrated circuits. It features a standard TSSOP package configuration suitable for surface-mount applications.

Feature Summary

• Provides eight independent buffered output channels for signal distribution
• Operates with a single 3.3V power supply rail
• CMOS technology ensures low power consumption and high noise immunity

Applications

• General-purpose digital signal buffering in embedded systems
• Address bus driving in memory interface circuits
• Data line isolation in communication modules

Procurement Notes

Verify the manufacturer designation, as IDT was acquired by Renesas Electronics. Confirm the specific suffix 'E4PY' matches the required package type and lead-free status. Check RoHS compliance documentation directly from the supplier or official datasheet, as availability varies between original IDT stock and current Renesas production lines. Ensure the source provides valid traceability for automotive or industrial qualification if required.

Selection Notes

Select this component when an octal buffer is required for 3.3V logic levels. Compare against similar 74LVC244 variants based on package dimensions and thermal performance. Verify input/output voltage compatibility with the system's logic family. Consider pinout compatibility with existing PCB layouts before finalizing the part number choice.

Part Context

This part is part of the widely used 74LVC244 series of octal buffers. The 'AE4PY' suffix typically denotes specific packaging and environmental compliance attributes defined by the manufacturer. As IDT products transitioned to Renesas, cross-referencing with current Renesas catalogs is necessary for updated documentation and long-term supply assurance.

Replacement Considerations

Direct substitutes include other 74LVC244 variants from manufacturers like NXP or Texas Instruments, provided the pinout and electrical characteristics match. Verify that alternative parts support the same 3.3V operation and octal configuration. Check for any differences in drive strength or propagation delay that might affect circuit timing.
