74ALVT16244DGG,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ALVT16244DGG,118 is a 16-bit buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 2.3 V to 3.6 V and utilizes BiCMOS technology for high-speed performance. The device includes four output enables (1OE, 2OE, 3OE, 4OE) controlling four outputs each. It supports TTL level interfacing and features bus hold inputs to eliminate external pull-up resistors. The component is housed in a TSSOP48 package (SOT362-1).

Buffers, Drivers, Receivers, Transceivers FAQ

How does the bus hold feature function?

The bus hold inputs maintain a defined logic state without external components, preventing floating inputs and reducing noise susceptibility on unused data lines.

What is the purpose of the IOFF circuitry?

The IOFF circuitry disables the outputs during power-down, preventing damaging backflow current through the device when it is not powered.
