74LVCH16245ADGG:11

Overview

The Nexperia 74LVCH16245ADGG:11 is a 16-bit bus transceiver with 3-state outputs, housed in a TSSOP48 package (SOT362-1). It operates on a supply voltage range of 1.2 V to 3.6 V and features inputs tolerant to 5.5 V. The device includes two output enables and two direction control inputs. It supports partial power-down via IOFF circuitry and incorporates bus hold on data inputs. Operating temperatures range from -40 °C to +125 °C.

Feature Summary

• Bus hold functionality on all data inputs eliminates the need for external pull-up resistors.
• IOFF circuitry prevents damaging backflow current during partial power-down applications.
• Schmitt-trigger action at all inputs provides tolerance for slower input rise and fall times.

Applications

• Mixed 3.3 V and 5 V environments
• Partial power-down applications
• Translators between different logic levels

Procurement Notes

Verify the specific ordering suffix ':11' against official Nexperia documentation to confirm packaging details such as reel or cut tape specifications. Ensure the component status aligns with project requirements, as availability may vary by region and distributor.

Selection Notes

Select this component when a 16-bit bidirectional interface is required with 5 V tolerant inputs. The LVCH series offers low power dissipation and direct TTL level interfacing. Verify that the TSSOP48 package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the 74LVCH16245A family of 16-bit bus transceivers. It shares functional similarities with the 74LVC16245A but includes specific bus hold features characteristic of the LVCH variant. The ADGG designation indicates the TSSOP48 plastic thin shrink small outline package.

Replacement Considerations

The 74LVC16245ADGG is a related variant within the same datasheet but lacks the bus hold feature found in the LVCH version. Verify functional equivalence regarding input holding capabilities before substitution.
