SN74LVC162244ADLG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC162244ADLG4 is a 16-bit buffer and driver with 3-state outputs from the Texas Instruments LVC family. It operates within a supply voltage range of 1.65 V to 3.6 V and features inputs tolerant up to 5.5 V, facilitating mixed-mode signal operation in 3.3-V/5-V systems. The device provides a maximum propagation delay of 4.4 ns at 3.3 V and includes equivalent 26-Ω series resistors on output ports to minimize overshoot and undershoot without external components. It supports live insertion and partial power-down modes via Ioff circuitry.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation by accepting input voltages up to 5.5 V while operating at lower supply voltages.
• Includes integrated output series resistors to reduce signal overshoot and undershoot during transitions.
• Features Ioff circuitry to prevent damaging backflow current when the device is in partial power-down mode.

• Motor drive systems
• Network switch interfaces
• Power infrastructure control

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (SSOP, TSSOP, or TVSOP) matches the design footprint, as the 'DL' suffix indicates SSOP. Confirm RoHS compliance and lead finish specifications against the latest TI orderable addendum. Ensure ESD handling protocols are followed due to MOS gate sensitivity. Cross-reference the full part number including any G4 environmental suffixes for accurate procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for high-density bus-oriented applications requiring 16-bit buffering. It is suitable for designs needing down-voltage translation between 5-V and 3.3-V domains. Consider the 26-Ω internal resistance for impedance matching requirements. Verify that the 12 mA sink capability meets load demands and that the 4 independent OE pins align with bus segmentation needs.
