SN74LVC162244ADGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC162244ADGVR is a 16-bit buffer and driver featuring 3-state outputs, designed for operation within a supply voltage range of 1.65 V to 3.6 V. It supports mixed-mode signal operation with inputs accepting voltages up to 5.5 V while powered by lower voltages. The device includes equivalent 26-ohm series resistors in the output ports to minimize overshoot and undershoot without requiring external components. It offers a maximum propagation delay of 4.4 ns at 3.3 V and provides Ioff circuitry to support live insertion and partial power-down modes.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial power-down scenarios?

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?

The output ports include equivalent 26-ohm series resistors designed to reduce overshoot and undershoot, thereby eliminating the need for external resistors in most applications.
