CLVTH16240IDGGREP

Overview

The CLVTH16240IDGGREP is a 16-bit buffer and driver manufactured by Texas Instruments, utilizing Advanced BiCMOS (ABT) technology. It operates within a supply voltage range of 2.7 V to 3.6 V and supports mixed-mode signal operation with 5-V input and output voltages while powered at 3.3 V. The device features inverting outputs and symmetrical active-low output-enable inputs. It provides high-level output current of -32 mA and low-level output current of 64 mA. Propagation delay is typically 3.5 ns at 3.3 V. It includes Ioff and power-up 3-state support for hot insertion.

Feature Summary

• Supports mixed-mode signal operation allowing 5-V input and output voltages during 3.3-V VCC operation
• Provides Ioff and power-up 3-state functionality to prevent damaging backflow currents and driver conflicts during hot insertion
• Features active bus-hold circuitry on data inputs to maintain valid logic levels without external pullup or pulldown resistors
• Utilizes distributed VCC and GND pins to minimize high-speed switching noise

Applications

• Three-state memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm that SN74LVTH16240DGGR is the designated direct substitute. Ensure design reviews account for the discontinuation timeline and validate pin compatibility with existing layouts. Source replacement components from authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component for applications requiring 16-bit buffering with inverting logic and 3.3-V operation. It is suitable for systems needing tolerance to 5-V signals on inputs and outputs. Consider the ABT technology for low static-power dissipation. Verify that the TSSOP-48 package fits the PCB constraints. Evaluate the need for hot-insertion capabilities provided by the Ioff feature.

Part Context

This part belongs to the SN74LVTH16240-EP family, which is part of the Texas Instruments Widebus family. It is designed specifically for low-voltage 3.3-V VCC operation but maintains TTL interface compatibility. The device improves performance and density compared to standard logic buffers. It is manufactured using state-of-the-art Advanced BiCMOS technology optimized for 3.3-V systems.

Replacement Considerations

SN74LVTH16240DGGR is listed as a direct substitute.
