74LVC162244ADGVJ

Overview

The Nexperia 74LVC162244ADGVJ is a 16-bit buffer and line driver featuring integrated 30 Ω series termination resistors and 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V, with inputs tolerant up to 5.5 V. The device supports four independent output enables (1OE, 2OE, 3OE, 4OE) controlling four channels of four bits each. It includes IOFF circuitry for partial power-down protection and Schmitt-trigger inputs for noise immunity. The component is housed in a TVSOP48 package (SOT480-1) and functions across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Integrated 30 Ohm series termination resistors on all data lines
• IOFF circuitry prevents damaging backflow current during partial power-down
• Schmitt-trigger action provides tolerance for slow input rise and fall times
• Multibyte flow-through architecture with low inductance multiple power and ground pins

Applications

• Mixed 3.3 V and 5 V logic environments
• Partial power-down applications requiring backflow prevention
• High-speed bus buffering with controlled impedance requirements

Procurement Notes

Verify the specific ordering suffix 'VJ' against official Nexperia documentation to confirm tape-and-reel packaging specifications and manufacturing site details. Ensure the selected variant matches the required TVSOP48 package dimensions and lead pitch. Confirm compliance with relevant environmental directives such as RoHS and REACH through the manufacturer's latest product status reports before finalizing procurement.

Selection Notes

Select this component when designing systems requiring 16-bit buffering with built-in series termination to minimize signal reflections. The 5 V tolerant inputs allow direct interfacing with legacy 5 V logic without level shifters. Consider the TVSOP48 package constraints regarding thermal dissipation and board space. Verify that the operating voltage aligns with the 1.2 V to 3.6 V specification for optimal performance.

Part Context

This part belongs to the 74LVC162244A family of 16-bit buffers and line drivers manufactured by Nexperia. It shares functional similarities with the 74LVCH162244A but lacks the bus hold feature found in the LVCH variant. The device is designed for high-density digital applications where signal integrity and power management are critical. It complements other LVC series logic components for system expansion.

Replacement Considerations

The 74LVC162244ADGG is a pin-compatible alternative in the TSSOP48 package. The 74LVCH162244ADGV offers identical functionality but includes bus hold circuits on data inputs. Verify package compatibility and electrical characteristics before substitution.
