74LVCH16244ADGG,11

Overview

The Nexperia 74LVCH16244ADGG,11 is a 16-bit buffer and line driver featuring 3-state outputs housed in a 48-lead TSSOP package (SOT362-1). It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs up to 5.5 V. The device includes four independent output enables and bus hold circuitry on all data inputs. It complies with JEDEC standards for various voltage ranges and offers ESD protection exceeding 2000 V HBM.

Feature Summary

• Features 5 V tolerant inputs and outputs for direct interfacing with 5 V logic devices
• Includes IOFF circuitry to prevent damaging backflow current during partial power-down states
• Integrates bus hold circuitry on all data inputs to eliminate the need for external pull-up resistors

Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Buffering high-speed data buses in computing systems
• Driving transmission lines in telecommunications equipment

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the temperature grade aligns with system requirements. Ensure the component status is active before finalizing procurement plans. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit risks.

Selection Notes

Select this component when 16-bit buffering with 5 V tolerance is required. The LVCH series provides Schmitt-trigger action for slower input transitions. Verify that the TSSOP48 package fits the PCB layout constraints. Consider the low power consumption characteristics for battery-operated applications.

Part Context

This part belongs to the Nexperia 74LVC/LVCH family of 16-bit buffers. It shares functional similarities with the 74LVC16244A but includes enhanced bus hold features. The ADGG suffix specifically denotes the TSSOP48 plastic thin shrink small outline package with a 6.1 mm body width.

Replacement Considerations

The 74LVC16244ADGG:11 serves as a compatible alternative. Verify pinout compatibility and electrical specifications before substitution.
