SN74ALVCH162525DGG

Overview

The SN74ALVCH162525DGG is an 18-bit registered bus transceiver from Texas Instruments, housed in a 56-pin SSOP package. It features 3-state outputs and operates within a supply voltage range of 2.7 V to 3.6 V. The device supports bidirectional data transfer with integrated latching capability for stable signal holding. Designed for low-voltage CMOS technology, it ensures high noise immunity and fast switching speeds suitable for complex digital systems requiring reliable data retention and translation.

Feature Summary

• Integrates 18-bit register functionality to latch and hold data independently of input changes
• Provides bidirectional bus transmission with 3-state output control for efficient line sharing
• Utilizes advanced low-voltage CMOS technology to minimize power consumption while maintaining performance

Applications

• High-density memory interface circuits requiring data buffering
• Complex digital logic systems needing isolated data storage during bus operations
• Portable electronic devices where low power consumption and small form factor are critical

Procurement Notes

Verify the specific package variant and tape/reel specifications against the official datasheet before ordering. Ensure that the operating voltage requirements align with your system design, as this component is optimized for the 2.7 V to 3.6 V range. Confirm compatibility with your PCB footprint, specifically the 56-pin SSOP dimensions, to avoid assembly issues.

Selection Notes

Select this component when 18-bit data latching is required alongside bidirectional bus driving capabilities. It is suitable for applications demanding low power operation in portable electronics. Consider the 56-pin SSOP package constraints regarding board space and thermal management. Compare propagation delays and drive strength against other ALVC series devices if higher speed or different pin counts are needed.

Part Context

This part belongs to the Texas Instruments ALVCH series, which combines low-voltage CMOS performance with latch functionality. The ALVCH family is designed for applications requiring both data storage and bus interfacing in a single package. It serves as a bridge between microprocessors and peripheral devices, offering robust signal integrity in low-voltage environments.

Replacement Considerations

Check for direct cross-references such as HD74ALVCH162525AT from Hitachi. Verify pinout compatibility and electrical characteristics before substituting. Ensure the alternative device supports the same 18-bit width and 56-pin SSOP package to maintain mechanical fit.
