SN74ALVC16244ADL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVC16244ADL is a 16-bit buffer and driver with 3-state outputs, manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features a maximum propagation delay of 3 ns at 3.3 V. The device provides ±24 mA output drive capability at 3.3 V and includes latch-up performance exceeding 250 mA per JESD 17. It is housed in a 48-pin SSOP (DL) package and supports an operating free-air temperature range of -40 °C to 85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base model number corresponds to the SSOP variant. Confirm the moisture sensitivity level and lead finish details against the latest packaging addendum to ensure compatibility with assembly processes. Ensure all unused inputs are tied to VCC or GND to maintain proper operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide data path requires buffering with low propagation delay and strong drive current. It is suitable for applications needing operation across a wide voltage range from 1.65 V to 3.6 V. Consider the SSOP package constraints regarding pin count and thermal impedance if space is limited.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus family, which focuses on improving performance and density for digital logic applications. It is part of the ALVC series, designed specifically for low-voltage CMOS operations. The ADL suffix indicates the SSOP package configuration, distinguishing it from other available form factors like TSSOP or FBGA.

Buffers, Drivers, Receivers, Transceivers FAQ

How should unused inputs be handled?

All unused inputs must be held at VCC or GND to ensure proper device operation.

What is the recommended method to ensure high-impedance state during power cycles?

The OE input should be tied to VCC through a pullup resistor, with the minimum value determined by the driver's current-sinking capability.
