74LVC16245ADGVJ

Overview

The 74LVC16245ADGVJ is a 16-bit bus transceiver with 3-state outputs from the Nexperia LVC/LVCH family. It supports dual 8-bit or single 16-bit configurations via two output enables and direction inputs. Operating on a 1.2 V to 3.6 V supply, it features 5.5 V tolerant inputs for mixed-voltage translation. The device includes Schmitt-trigger inputs, IOFF circuitry for partial power-down protection, and bus hold functionality in LVCH variants.

Feature Summary

• Supports bidirectional data transmission between 3.3 V and 5 V logic environments
• Incorporates IOFF circuitry to prevent damaging backflow current during power-down
• Features Schmitt-trigger inputs for tolerance of slow rise and fall times
• Provides active bus hold on data inputs to eliminate external pull-up resistors

Applications

• Mixed voltage level translation between 3.3 V and 5 V systems
• Partial power-down applications requiring backflow current prevention
• High-density digital data bus interfacing
• Systems requiring noise immunity against slow signal transitions

Procurement Notes

Verify the specific suffix 'J' against official Nexperia documentation to confirm package variant and tape-and-reel specifications. Ensure the ordered part matches the required temperature range and electrical characteristics defined in the product data sheet before finalizing procurement.

Selection Notes

Select this component when designing interfaces between 3.3 V and 5 V logic domains requiring 16-bit width. Choose the LVCH variant if bus hold functionality is needed to manage floating inputs without external resistors. Verify that the TVSOP48 package dimensions fit the target PCB layout constraints.

Part Context

This device belongs to the Nexperia 74LVC16245A/74LVCH16245A family of 16-bit bus transceivers. It shares functional similarities with other members like the 74LVC16245ADGG but differs in package type. The ADGVJ designation specifically indicates the TVSOP48 plastic thin shrink small outline package variant.

Replacement Considerations

The 74LVC16245ADGG serves as a pin-compatible alternative using the TSSOP48 package. Verify package dimensions and lead pitch compatibility before substitution.
