74LVCH162244ADL:11

Overview

The Nexperia 74LVCH162244ADL:11 is a 16-bit buffer and line driver featuring 30 Ohm 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 contains four output enables controlling 3-state outputs, where a HIGH on nOE forces a high-impedance OFF-state. Inputs utilize Schmitt-trigger action for noise immunity. The LVCH variant includes bus hold circuitry on all data inputs to maintain valid logic levels without external pull-up resistors.

Feature Summary

• Integrated 30 Ohm series termination resistors for signal integrity
• Bus hold functionality on data inputs eliminates need for external pull-ups
• IOFF circuitry prevents backflow current during partial power-down
• Schmitt-trigger inputs provide tolerance for slow rise and fall times

Applications

• Mixed 3.3 V and 5 V environment translation
• Parallel data buffering in multibyte flow-through architectures
• Line driving with controlled impedance termination

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the ADL designation corresponds to the SSOP48 package which was removed from the standard product data sheet in revision v.8 (September 2021). Confirm current availability status directly with Nexperia or authorized distributors, as older package variants may be discontinued or superseded by TSSOP48 or TVSOP48 options.

Selection Notes

Select this component when designing systems requiring 16-bit parallel buffering with integrated termination. Ensure the application utilizes the LVCH variant if bus hold capability is necessary to manage floating inputs. Verify that the input signals remain within the 5.5 V tolerance limit and that the supply voltage stays between 1.2 V and 3.6 V for proper operation.

Part Context

This part belongs to the 74LVC/LVCH162244A family of 16-bit buffers. While the ADL package (SSOP48) is referenced in historical documentation, recent datasheet revisions indicate removal of this specific package type in favor of TSSOP48 (DGG) and TVSOP48 (DGV). The functional core remains consistent across the family regarding voltage ranges and termination features.

Replacement Considerations

Public confirmed substitute part numbers include 74LVC162244ADGG:11 and 74LVCH162244ADGG:11 for the TSSOP48 package.
