SN74LVC16244ADGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16244A 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 environments by accepting input voltages up to 5.5 V while operating at lower VCC levels. The device provides a maximum propagation delay of 4.1 ns at 3.3 V and includes an Ioff feature that prevents excessive current draw during partial-power-down or live insertion scenarios. It is housed in a 48-pin TSSOP package.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function?

The Ioff feature allows voltages to be present on the inputs and outputs even when VCC is at 0 V, thereby supporting partial-power-down mode and preventing damage during live insertion.

What is the maximum input voltage tolerance?

The inputs accept voltages up to 5.5 V, allowing the device to interface with 5-V devices while the VCC supply operates at lower voltages such as 3.3 V.
