74LVCH16541ADGG:51

Overview

The 74LVCH16541ADGG:51 is a 16-bit buffer and line driver featuring 3-state outputs, manufactured by Nexperia (formerly NXP). It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs up to 5.5 V for mixed-voltage interfacing. The device utilizes a TSSOP48 package (SOT362-1) with dual output enable controls. It includes bus hold functionality on data inputs to eliminate external pull-up resistors and complies with JEDEC standards for low-voltage CMOS logic.

Feature Summary

• Provides 5 V tolerant inputs and outputs for direct interfacing with 5 V logic systems
• Features bus hold circuits on all data inputs to maintain stable states without external components
• Maintains high-impedance outputs when the supply voltage is zero for safe power-off operation
• Utilizes low inductance multiple power and ground pins to minimize noise and ground bounce

Applications

• Mixed 3.3 V and 5 V system interconnects
• High-density memory buffering applications
• Clock distribution and signal driving in computing environments

Procurement Notes

Verify that the ordering suffix :51 corresponds to the specific reel or tape configuration required for your assembly process. Confirm the manufacturer origin, as the product was transferred from NXP to Nexperia. Ensure the TSSOP48 package variant matches your PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring 16-bit parallel data transmission between different voltage domains. The LVCH series offers lower power consumption compared to older LVC families while maintaining compatibility with standard TTL levels. Consider the thermal derating characteristics if operating near the maximum ambient temperature limits specified in the datasheet.

Part Context

This part belongs to the 74LVCH16541A family of 16-bit buffers and line drivers. The 'DGG' designation indicates the TSSOP48 plastic thin shrink small outline package. The ':51' suffix typically denotes a specific packaging quantity or reel type defined by the distributor or manufacturer's internal coding standards.

Replacement Considerations

Direct functional replacements include the 74LVCH16541ADL in SSOP48 packaging or other 74LVCH16541 variants within the same logical family. Verify pinout compatibility and package dimensions when substituting.
