IDT74ALVCH162825APF

Overview

The IDT74ALVCH162825APF is an 18-bit buffer and driver manufactured by Integrated Device Technology Inc. It belongs to the ALVCH series, designed for high-performance bus-oriented applications requiring low power consumption and wide operating voltage ranges. The component features a single output configuration with three-state outputs, facilitating efficient data transmission in complex digital systems while maintaining signal integrity across various logic families.

Feature Summary

• Provides 18-bit buffering and driving capabilities for high-density data buses
• Supports three-state outputs to enable multiple drivers on shared lines
• Designed for low-power CMOS operation compatible with standard logic levels

Applications

• High-speed data bus buffering in computing systems
• Memory interface drivers for address and data lines
• General-purpose logic level shifting between different voltage domains

Procurement Notes

Verify the manufacturer designation as IDT or Renesas Electronics, noting that Intersil was acquired by Renesas. Confirm the package type matches the 'PF' suffix specification. Ensure the datasheet aligns with the specific ALVCH series electrical characteristics. Check for RoHS compliance status if required by your manufacturing standards. Validate the part number against official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when an 18-bit wide buffer is required for bus isolation or signal strengthening. Consider the ALVCH series benefits for applications needing lower power dissipation compared to older LVCH variants. Evaluate the operating voltage range to ensure compatibility with the system's supply rails. Assess the pinout compatibility if replacing existing designs with similar footprint requirements.

Part Context

This device is part of the broader ALVCH family of low-voltage CMOS logic devices. It serves as a critical interconnect element in digital circuits, bridging high-drive requirements with low-power constraints. The integration of 18 bits into a single package reduces board space and simplifies routing compared to using multiple smaller buffers.

Replacement Considerations

Check for direct substitutes within the same ALVCH series from IDT/Renesas. Verify pin-to-pin compatibility with other 18-bit buffers like the 74ALVCH162825 equivalents from other vendors. Ensure electrical parameters such as propagation delay and drive strength meet the original design specifications.
