SN74LVCH16373ADL

Latches Overview

The SN74LVCH16373ADL is a 16-bit transparent D-type latch featuring three-state outputs, designed for operation within a 1.65 V to 3.6 V supply voltage range. It belongs to the Texas Instruments LVCH broadband bus series and utilizes a 48-pin SSOP package. The device supports mixed-mode signal operations, allowing compatibility with 5 V inputs while operating at lower voltages. Key electrical characteristics include a typical output ground bounce (VOLP) of less than 0.8 V and an output voltage undershoot (VOHV) greater than 2 V at 3.3 V. It offers high latch performance exceeding 250 mA per JESD78 Class II standards.

Latches Feature Summary

• Supports mixed-mode signal operations with 5 V input tolerance
• Bus-holding inputs eliminate external pull-up or pull-down resistors
• Ioff circuitry enables partial power-down mode protection
• High ESD protection ratings exceeding industry standards

Latches Applications

• Buffer registers in digital systems
• Work registers for data storage
• Bidirectional bus drivers
• Memory addressing circuits

Latches Procurement Notes

Verify the specific suffix 'ADL' corresponds to the 48-lead SSOP package configuration. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure the design accounts for the specified 1.65 V to 3.6 V operating range. Check for any specific handling requirements related to the surface-mount package type during assembly.

Latches Selection Notes

Select this component when a 16-bit latch with three-state outputs is required for low-voltage applications. It is suitable for designs needing mixed-signal interface capabilities between 3.3 V logic and 5 V peripherals. Consider the SSOP package constraints regarding board space and thermal dissipation. Verify that the bus-holding feature meets the system's input state requirements without external components.

Latches Part Context

This part is a member of the SN74LVCH16373A family, which provides 16-bit latching functionality. It shares functional similarities with other LVC and LVCH series devices but is optimized for lower voltage operation compared to standard 5 V logic families. The device serves as a key component in high-density digital interfaces requiring reliable data retention and bus isolation.

Latches Replacement Considerations

SN74LVCH16373ADLR is a tape-and-reel alternative in the same package. SN74LVCH16373ADGVR offers the same function in a TVSOP-48 package. SN74LVC16373ADLR is a parameter-equivalent option from the LVC series.
