SN74LVC162244AGRDR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC162244AGRDR is a 16-bit buffer and driver with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation. The device provides a maximum propagation delay of 4.4 ns at 3.3 V and includes equivalent 26-ohm series resistors in the output ports to minimize overshoot and undershoot without requiring external components.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation with 5-V input tolerance on all ports while operating at lower supply voltages
• Includes integrated output series resistors to reduce signal reflections and eliminate the need for external termination components
• Provides Ioff circuitry to prevent damaging backflow current during partial power-down or live insertion scenarios

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package marking and tape-and-reel specifications against the manufacturer's orderable addendum. Confirm that the GRD or ZRD package designation aligns with the required board layout constraints. Ensure compliance with RoHS and environmental standards specified in the product data sheet before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring high-density 16-bit buffering with low-voltage compatibility. The device is suitable for applications needing down-voltage translation between 3.3-V and 5-V domains. Consider the thermal resistance metrics and pin configuration options when evaluating PCB space and heat dissipation requirements for the target enclosure.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus family of logic ICs. It is designed to improve performance and density in memory address drivers, clock drivers, and bus-oriented receivers. The SN74LVC162244A serves as a non-inverting buffer that can be configured as four 4-bit buffers, two 8-bit buffers, or one single 16-bit buffer.
