SN74LVC162244ADL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC162244ADL 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, enabling mixed-mode signal operation in 3.3-V/5-V systems. The device provides symmetrical active-low output-enable inputs and includes equivalent 26-Ω series resistors on the outputs to reduce overshoot and undershoot without requiring external components. It supports live insertion and partial power-down modes via Ioff circuitry. The component is housed in a 48-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DL' corresponds to the SSOP-48 tube packaging configuration. Confirm RoHS compliance status and lead finish details against the latest TI Package Option Addendum. Ensure the procurement request matches the exact part number SN74LVC162244ADL to avoid confusion with tape-and-reel variants like ADLR or different package types such as DGG or DGV.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing high-density bus-oriented receivers or transmitters requiring 16-bit data handling. It is suitable for applications needing down-voltage translation between 5-V and 3.3-V domains. Consider its 5.5-V tolerant inputs if interfacing with legacy logic levels. Evaluate the SSOP-48 package dimensions against available PCB real estate constraints.

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 even if input signals are present.

What is the purpose of the internal series resistors on the outputs?

The outputs contain equivalent 26-Ω series resistors designed to reduce overshoot and undershoot, eliminating the need for external resistors in most applications.
