74LVCH16244ADGG:11

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74LVCH16244ADGG:11 is a 16-bit buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs up to 5.5 V, enabling direct interfacing with 5 V logic devices. The device includes IOFF circuitry for partial power-down protection and bus hold functionality on data inputs. It utilizes a 48-lead TSSOP plastic thin shrink small outline package (SOT362-1) and is rated for ambient temperatures from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides 5 V tolerant inputs and outputs for mixed-voltage system interfacing
• Includes IOFF circuitry to prevent damaging backflow current during power-down
• Features bus hold on all data inputs to eliminate the need for external pull-up resistors

Buffers, Drivers, Receivers, Transceivers Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Partial power-down applications requiring high-impedance output states
• Buffering and driving lines in multibyte flow-through architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required package variant. Confirm the temperature grade aligns with operational requirements. Ensure compatibility with existing PCB footprint dimensions for the TSSOP48 package. Check for any recent product change notices regarding assembly sites or labeling updates.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when 16-bit buffering with 5 V tolerance is required. The LVCH series offers bus hold features not present in the standard LVC version. Verify that the 3-state control inputs meet the system's enable/disable timing constraints. Consider the low inductance pin configuration for noise reduction in high-speed designs.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LVC/LVCH16244A family of 16-bit buffers. The 'H' designation indicates the inclusion of bus hold circuits on data inputs. It shares functional similarities with other 16-bit drivers but differs in input handling characteristics. The ADGG suffix specifically denotes the TSSOP48 package type.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74LVC16244ADGG:11 serves as a non-bus-hold alternative within the same package. Cross-reference pinouts carefully when substituting with variants lacking bus hold features.
