SN74ALVTH16244DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVTH16244DLR is a 16-bit buffer and line driver utilizing Advanced BiCMOS Technology (ABT) for 3.3-V operation, housed in a 48-pin SSOP package. It supports mixed-mode signal environments with 5-V I/O compatibility while operating on unregulated battery power down to 2.3 V. The device features high drive capability of -32 mA/64 mA and includes active bus-hold circuitry to maintain valid logic levels on floating inputs. Electrical characteristics specify a propagation delay of 2.6 ns at 3.3 V with a 50 pF load.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operations by interfacing 5-V input and output voltages with 3.3-V VCC systems.
• Features active bus-hold circuitry that eliminates the need for external pullup or pulldown resistors on data inputs.
• Provides Ioff and power-up 3-state functionality to support hot-insertion applications without damaging backflow currents.
• Includes auto-3-state capability that prevents bus current loading when the voltage at the output exceeds VCC.

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed-mode signal environments requiring TTL interface to 5-V systems
• Unregulated battery operation supporting voltages down to 2.3 V
• Hot-insertion applications utilizing Ioff and power-up 3-state protection

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized Texas Instruments channels or certified distributors. Confirm the specific DL suffix indicates the standard SSOP-48 plastic shrink small-outline package. Ensure compliance with RoHS directives and check for any product life cycle notices regarding obsolescence status before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 16-bit buffering with high drive strength and 5-V tolerance. Verify that the system operates within the recommended supply voltage range of 2.3 V to 3.6 V. Consider the thermal impedance of the SSOP-48 package if multiple units are deployed in dense layouts to ensure proper heat dissipation during continuous operation.
