SN74ALVTH32373KR

Overview

The SN74ALVTH32373KR is a Texas Instruments octal transparent D-type latch featuring three-state outputs, designed for 2.5-V and 3.3-V systems. It belongs to the ALVTH logic family, utilizing ABT technology to ensure low power consumption and high-speed operation. The device accepts eight D-type inputs and provides corresponding Q outputs with latching capability controlled by an enable signal. The KR suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Feature Summary

• Transparent D-type latch architecture allows data to pass directly from input to output when enabled.
• Three-state outputs facilitate direct connection to bus structures without external buffers.
• ABT technology provides high-speed performance while maintaining low static power dissipation.

Applications

• High-performance register files in digital signal processing systems
• Bus-oriented memory mapping applications
• Parallel-to-serial conversion interfaces

Procurement Notes

Verify the specific KR suffix configuration against the official datasheet to confirm tape-and-reel specifications. Ensure compatibility with standard surface-mount reflow profiles. Cross-reference the manufacturer's latest documentation for any updates on lead-free compliance or environmental declarations prior to final procurement decisions.

Selection Notes

Select this component for designs requiring fast switching speeds with minimal power usage in 3.3-V environments. The octal configuration reduces board space compared to individual latches. Verify that the system voltage levels align with the specified 2.5-V to 3.3-V operating range to ensure reliable logic threshold performance.

Part Context

This part is part of the ALVTH series, which bridges the gap between standard CMOS speed and low power consumption. It serves as a key building block for data storage and buffering in modern embedded systems. The octal layout simplifies routing for wide data buses in compact form factors.

Replacement Considerations

Check for SN74ALVTH32373DR or SN74ALVTH32373PW if different package types are required. Verify pinout compatibility before substituting with other octal latches from the same logic family.
