SN74LVCH16373ADLG4

Latches Overview

The SN74LVCH16373ADLG4 is a 16-bit transparent D-type latch manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 1.65 V to 3.6 V. The device is housed in a 48-pin LG package (TSSOP). It supports mixed-mode signal operations, allowing compatibility with 5-V inputs while operating at lower voltages. Key electrical characteristics include typical output ground bounce below 0.8 V and undershoot greater than 2 V at 3.3 V operation.

Latches Feature Summary

• Supports mixed-mode signal operations for interfacing 5-V data buses with 3.3-V systems
• Includes bus-hold circuitry on data inputs to eliminate the need for external pull-up or pull-down resistors
• Provides Ioff support enabling partial-power-down mode and back-drive protection during live insertion

Latches Applications

• High-density memory mapping applications
• Buffering and register functions in general-purpose digital circuits
• Clock-domain crossing synchronization

Latches Procurement Notes

Verify the specific suffix 'A' indicates an enhanced product version with improved specifications compared to standard variants. Confirm the 'LG' package designation corresponds to the 48-lead Thin Shrink Small Outline Package (TSSOP) variant. Ensure compliance requirements such as RoHS status match project specifications before finalizing procurement orders.

Latches Selection Notes

Select this component when designing systems requiring 16-bit latching with high-speed performance and low voltage operation. It is suitable for applications needing isolation between input data and output drivers. Consider the 48-pin TSSOP footprint constraints and thermal dissipation requirements associated with dense surface-mount layouts.

Latches Part Context

This part belongs to the Texas Instruments LVCH (Low-Voltage CMOS High-Speed) logic family. It is functionally related to other 16-bit latches like the SN74LVC16373 but offers optimized performance for 3.3-V systems with mixed-signal capabilities. It serves as a critical interface element in complex digital architectures requiring reliable data storage and transfer.
