SN74ALVTH16373GR

Overview

The SN74ALVTH16373GR is a 16-bit transparent D-type latch manufactured by Texas Instruments. It features tri-state outputs and operates within a supply voltage range of 2.5 V to 3.6 V. The device utilizes the ALVTH logic series, providing low static power consumption and high-speed performance with propagation delays typically around 4.3 ns at 3.3 V. Packaged in a TSSOP-48 surface-mount format, it supports industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include an output drive capability of 32 mA at low levels and 24 mA at high levels, ensuring robust signal integrity for bus-oriented applications.

Feature Summary

• Provides 16-bit data storage with transparent latching functionality controlled by an enable input.
• Features tri-state outputs that allow direct connection to system buses without external drivers.
• Designed for low-voltage operation compatible with standard 3.3 V logic systems.

Applications

• Bus-oriented memory mapping
• Clock buffering and driving
• Cache memory systems

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with target voltage levels and environmental operating conditions before integration. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or pin configurations.

Selection Notes

Select this component when a 16-bit latch with tri-state outputs is required for 3.3 V systems. Consider the ALVTH series for its balance of speed and power efficiency compared to older logic families. Verify that the TSSOP-48 package fits the board layout constraints and thermal requirements of the design.

Part Context

This part belongs to the Texas Instruments 74ALVTH logic family, which is optimized for low-voltage applications. It serves as a successor to earlier 3.3 V latch technologies, offering improved switching speeds and lower power dissipation. The 16373 designation specifically indicates a 16-bit configuration with tri-state capabilities suitable for wide data buses.

Replacement Considerations

Check for SN74ALVCH16373DGGR as a potential alternative within the same product line. Verify functional equivalence regarding voltage ranges and output drive strengths before substitution.
