SN74LVC162244ADLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC162244ADLR is a 16-bit buffer and line driver featuring 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and accepts input voltages up to 5.5 V, facilitating mixed-mode signal operation. The device provides symmetrical active-low output-enable inputs and includes equivalent 26-ohm series resistors in the output ports to minimize overshoot and undershoot without requiring external components. It supports live insertion and back-drive protection via Ioff circuitry. The component is housed in an SSOP-48 package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple physical configurations. Confirm RoHS compliance status and lead finish specifications against the manufacturer's latest orderable addendum. Ensure the selected variant aligns with the intended thermal management requirements and moisture sensitivity level ratings for the assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring high-density 16-bit data buffering or address driving. It is suitable for applications needing down-voltage translation between 5-V and 3.3-V domains. Consider the SSOP-48 package constraints regarding board space and thermal dissipation. Verify that the system frequency does not exceed the propagation delay limits specified for the target supply voltage.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVC162244A family of widebus buffers. It is designed to improve performance and density in memory address drivers, clock drivers, and bus-oriented receivers. The family offers flexibility to function as four 4-bit buffers, two 8-bit buffers, or a single 16-bit buffer depending on the enable pin configuration.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial power-down conditions?

The Ioff circuitry automatically disables the outputs when VCC is 0 V, preventing damaging current backflow through the device during power-down states.

Is external resistance required for the output ports?

No, the output ports include equivalent 26-ohm series resistors designed to reduce overshoot and undershoot, eliminating the need for external resistors.
