74LVCH162374ADGG,1

Overview

The 74LVCH162374ADGG,1 is a dual 8-bit D-type flip-flop with 3-state outputs from the LVCH logic family. It operates within a supply voltage range of 1.2 V to 3.6 V and features 5 V tolerant inputs and outputs for mixed-signal interfacing. The device utilizes a TSSOP-48 package and supports an operating temperature range from -40 °C to +125 °C. Key electrical characteristics include a propagation delay of 3.8 ns at 3.3 V and output drive capabilities of ±12 mA. It includes I_OFF circuitry for partial power-down protection.

Feature Summary

• Integrates dual 8-bit D-type flip-flops with 3-state outputs in a single package
• Provides 5 V tolerant inputs and outputs for direct interface with mixed voltage systems
• Includes I_OFF circuitry to prevent damaging backflow current during partial power-down
• Features bus hold on data inputs to eliminate the need for external pull-up resistors

Applications

• Parallel data storage in high-speed digital systems
• Interface buffering between 3.3 V and 5 V logic domains
• Clock synchronization and data register applications
• Mixed-voltage system architecture translation

Procurement Notes

Verify the specific ordering suffix ADGG,1 to ensure correct packaging and tape-and-reel configuration as defined by Nexperia. Confirm that the component meets RoHS compliance requirements for your region. Check the official longevity program status, as this part may be subject to production end-of-life notifications. Ensure that the TSSOP-48 package dimensions align with your PCB footprint specifications before finalizing procurement.

Selection Notes

Select this component when dual 8-bit storage with 3-state control is required in a compact surface-mount package. The LVCH series offers low power consumption suitable for battery-operated devices. Verify that the 1.2 V minimum supply voltage meets your system's lowest operating condition. Consider the 3.8 ns propagation delay for timing constraints in your clock domain. The integrated bus hold feature simplifies design by removing external resistor requirements for unused inputs.

Part Context

This device belongs to the Nexperia LVCH (Low Voltage CMOS High-performance) logic family, designed for high-speed operation with low power dissipation. It is part of the broader 74LVCH16xxx series of 16-bit wide logic components. The ADGG,1 designation indicates the TSSOP-48 plastic small-outline package with specific reel packaging. This family is engineered to replace older LVC/LCX/Z series parts while offering improved performance and voltage tolerance.

Replacement Considerations

The 74LVCH162374ADG is a compatible alternative from NXP Semiconductors with identical logical function and pinout. Verify package compatibility between TSSOP-48 variants if substituting. Cross-reference electrical parameters such as propagation delay and output current to ensure system performance is maintained. Confirm that the replacement part supports the same 5 V tolerant input/output specifications.
