SN74ALVTH16373DLR

Overview

The SN74ALVTH16373DLR is a 16-bit transparent D-type latch with 3-state outputs from the ALVTH logic series. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an operating temperature range of -40°C to +85°C. The device features propagation delays of 4.3 ns and 3.6 ns, with a maximum static current of 40 uA. Output drive capabilities include 32 mA low-level and -24 mA high-level currents. It is housed in a TSSOP-48 surface-mount package.

Feature Summary

• Provides 16-bit data storage with transparent latching functionality for direct input-to-output transmission when enabled.
• Features 3-state outputs that allow connection to a shared bus structure without external drivers.
• Supports low-voltage operation down to 1.65 V, enabling compatibility with modern low-power system architectures.

Applications

• Parallel data buffering in embedded systems
• Bus-oriented memory mapping circuits
• I/O port expansion modules

Procurement Notes

Verify the specific suffix 'DLR' corresponds to the TSSOP-48 package and reel packaging configuration required for your assembly process. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design specifications align with the absolute maximum ratings defined in the datasheet to prevent device damage during operation.

Selection Notes

Select this component when 16-bit parallel latching is required at low voltages. Compare against the SN74ALVCH16373 series if higher speed or different electrical characteristics are needed. Verify pinout compatibility with existing PCB layouts before finalizing the bill of materials.

Part Context

This part belongs to the Texas Instruments SN74ALVTH family of advanced low-voltage CMOS logic devices. These components are designed for high-density applications requiring low power consumption and wide voltage flexibility. The 16-bit latch variant specifically addresses needs for large parallel data handling in compact form factors.

Replacement Considerations

SN74ALVCH16373DGGR is a documented substitute offering similar functionality within the same logic family.
