SN74ALVTH16244DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVTH16244DL is a 16-bit buffer and line driver utilizing Advanced BiCMOS Technology (ABT). It operates at supply voltages of 2.5 V or 3.3 V, with inputs compatible with 5-V TTL logic levels. The device features three-state outputs and provides high drive capability, specified as -32 mA for high-level output current and 64 mA for low-level output current. It supports mixed-mode signal operation, allowing 5-V input and output voltages while powered by 3.3 V. The component is housed in a 48-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation with 5-V I/O compatibility
• Features active bus-hold circuitry to maintain valid logic levels on floating data inputs
• Includes Ioff and power-up three-state functionality to prevent damaging backflow during hot insertion
• Provides latch-up protection exceeding 250 mA per JESD 17

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed-mode signal environments requiring 5-V to 3.3-V translation
• Hot-insertion applications utilizing Ioff and power-up three-state capabilities
• Unregulated battery operation down to 2.3 V

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DL' corresponds to the SSOP-48 plastic shrink small-outline package. Confirm that the part status is marked as obsolete in current Texas Instruments catalogs, as this impacts long-term availability and production support. Ensure design-in requirements align with the -40°C to +85°C operating temperature range specified for the SN74 series variant.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit buffering with 5-V tolerant inputs and 3.3-V operation. The ABT technology offers lower static power dissipation compared to standard CMOS. Consider the high drive capability (-32 mA/64 mA) if driving heavy capacitive loads. Verify that the SSOP-48 package dimensions fit the target PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Widebus family of 16-bit buffers and drivers. It is part of the ALVTH series, which combines 3.3-V operation with 5-V I/O compatibility. The SN74 prefix indicates commercial temperature grading, distinguishing it from the SN54 military-grade counterpart. The DL suffix specifically denotes the 48-pin SSOP package format.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74ALVTH16244GR (TSSOP package) or SN74ALVTH16244VR (TVSOP package) for pin-compatible alternatives within the same logic family.
