74LVCH16374ADGG:11

Overview

The Nexperia 74LVCH16374ADGG:11 is a 16-bit D-type flip-flop with 3-state outputs, belonging to the LVCH logic family. It operates within a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device is housed in a TSSOP-48 package (SOT362) and supports surface mount installation. It includes I_OFF circuitry for partial power-down protection, preventing damaging backflow currents. The component complies with JEDEC standards for various voltage ranges and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• 16-bit D-type flip-flop architecture with 3-state outputs for efficient bus interfacing.
• Overvoltage tolerant inputs allow direct interface with 5 V devices while operating at lower voltages.
• Integrated I_OFF circuitry enables safe partial power-down mode by disabling outputs.
• Schmitt-trigger action on inputs ensures tolerance for slow rise and fall times.

Applications

• Parallel I/O expansion in mixed 3.3 V and 5 V environments.
• Mobile and portable equipment requiring low power consumption.
• Consumer electronics utilizing high-density logic interfaces.
• Automotive applications requiring AEC-Q100 qualified components.

Procurement Notes

Verify the specific ordering suffix :11 against the manufacturer's current datasheet to confirm packaging details and availability status. Ensure that the TSSOP-48 package dimensions align with the target PCB footprint requirements. Confirm compliance with relevant environmental directives such as RoHS and REACH for the intended market. Cross-reference the part number with official Nexperia distributors to validate authenticity and supply chain integrity before finalizing procurement orders.

Selection Notes

Select this component when a 16-bit storage solution with 3-state output control is required in space-constrained designs. The LVCH series is appropriate for applications needing compatibility between 1.2 V and 3.6 V logic levels with 5 V input tolerance. Consider the TSSOP-48 package if surface mount density is a priority. Evaluate the I_OFF feature necessity for systems undergoing partial power-down cycles to prevent backpowering issues.

Part Context

This device is part of Nexperia's extensive 74LVCH portfolio, designed for low-voltage CMOS applications. The LVCH family bridges the gap between standard LVC performance and enhanced noise immunity. The ADGG variant specifically denotes the TSSOP-48 package configuration. This series is widely used in digital signal processing and memory interface circuits where data latching and tri-state buffering are essential functions.

Replacement Considerations

Direct substitutes include other 16-bit D-type flip-flops with 3-state outputs from the same logic family, such as the 74LVC16374ADGG. Verify pinout compatibility and electrical characteristics before substitution. Alternative packages like SO48 may be considered if form factor changes are acceptable. Always consult the latest datasheets to ensure functional equivalence regarding voltage tolerances and switching speeds.
