74LVT16373ADGG,112

Latches Overview

The 74LVT16373ADGG,112 is a 3.3 V 16-bit transparent D-type latch with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 2.7 V to 3.6 V and supports input voltages up to 5.5 V. The device features BiCMOS technology providing an output capability of +64 mA/–32 mA. Propagation delays from data inputs to outputs range from 0.5 ns to 3.9 ns depending on voltage. It includes bus-hold inputs, power-up reset, and IOFF circuitry for partial power-down operation.

Latches Feature Summary

• Features 3-state outputs and overvoltage tolerant inputs up to 5.5 V for mixed-voltage interfacing.
• Includes bus-hold data inputs to eliminate the need for external pull-up resistors on unused lines.
• Supports live insertion/extraction and provides IOFF circuitry for partial power-down mode operation.

Latches Applications

• Bus-oriented applications requiring 16-bit data storage
• Mixed 3.3 V and 5 V logic environments
• Systems requiring live insertion or extraction capabilities

Latches Procurement Notes

Verify the manufacturer designation as Nexperia rather than NXP USA Inc., as the component is produced under the Nexperia brand. Confirm the package type is TSSOP48 (SOT362-1) and check that the ordering suffix matches the specific reel or cut tape configuration required for your assembly process. Ensure compatibility with the 2.7 V to 3.6 V supply range.

Latches Selection Notes

Select this component when a 16-bit transparent latch with high drive current (+64 mA) is required. It is suitable for designs needing direct interface with TTL levels and overvoltage tolerant inputs. Consider the TSSOP48 package constraints and the specific propagation delay requirements across the 2.7 V to 3.6 V operating range.

Latches Part Context

This part belongs to the 74LVT series of logic ICs, specifically designed for 3.3 V applications. It functions as a dual 8-bit or single 16-bit latch. The ADGG suffix indicates the TSSOP48 plastic thin shrink small outline package. It is a production-grade product specified for industrial temperature ranges.

Latches Replacement Considerations

Check for equivalent parts in the 74LVT series from other manufacturers such as onsemi or Texas Instruments. Verify pinout compatibility and electrical specifications like propagation delay and output drive current before substitution.

Latches FAQ

What is the function of the bus-hold inputs?

The bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs at a defined logic level.

Can this device be used in mixed 3.3 V and 5 V systems?

Yes, the inputs are overvoltage tolerant to 5.5 V, allowing direct interfacing with 5 V devices while operating on a 3.3 V supply.
