74LVCH16344AXPA

Overview

The IDT74LVCH16344AXPA is a 3.3V CMOS octal buffer and driver manufactured by Integrated Device Technology Inc. It belongs to the 74LVCH series, designed for high-speed digital applications requiring robust signal integrity. The component features eight non-inverting buffers with three-state outputs, allowing for efficient bus-oriented memory and address driving. It operates within a standard voltage range suitable for modern low-power systems.

Feature Summary

• Provides eight non-inverting buffer channels for signal conditioning
• Features three-state outputs to facilitate bus-driven architectures
• Designed for 3.3V CMOS logic compatibility

Applications

• Bus-oriented memory addressing
• Clock distribution networks
• High-speed data line buffering

Procurement Notes

Verify the manufacturer part number against official IDT or Renesas documentation to ensure authenticity. Confirm that the specific suffix 'XPA' matches the required package type and tape-and-reel specifications for your assembly process. Check RoHS compliance status as indicated in the latest datasheet, noting that some legacy listings may have varying environmental declarations. Ensure the supplier provides traceable origin for critical electronic components.

Selection Notes

Select this component when designing systems requiring an octal buffer with three-state control at 3.3V logic levels. It is appropriate for applications needing high drive capability on address buses or clock lines. Consider the operating temperature range and package dimensions during PCB layout. Verify input/output voltage thresholds match the connected logic family to ensure reliable signal transmission without level shifting requirements.

Part Context

This device is part of the broader 74LVCH family of high-speed CMOS logic devices. The 74LVCH series offers improved performance over standard LVCMOS while maintaining backward compatibility with existing designs. IDT, now part of Renesas Electronics, produces these components for industrial and consumer electronics markets focusing on signal integrity and power efficiency.

Replacement Considerations

Check for direct substitutes such as the 74LVC244AE4Q from IDT/Renesas, which shares similar octal buffer functionality. Verify pinout compatibility and electrical characteristics before substitution. Other manufacturers may offer equivalent parts under different naming conventions; always cross-reference datasheets for parameter alignment.
