SN74ALVTH16601VR

Overview

The SN74ALVTH16601VR is an 18-bit universal bus transceiver utilizing Advanced BiCMOS (ABT) technology. It supports 2.5-V and 3.3-V VCC operation with 5-V tolerant inputs and outputs. The device integrates D-type latches and flip-flops for transparent, latched, clocked, or clock-enabled modes. It features high-drive outputs of -24/24 mA at 2.5 V and -32/64 mA at 3.3 V. Operating temperature range is -40°C to +85°C. Package is TVSOP-56.

Feature Summary

• Combines D-type latches and flip-flops for flexible data flow control in transparent, latched, clocked, or clock-enabled modes.
• Supports mixed-mode signal operation with 5-V input and output voltage tolerance while operating at 2.3 V to 3.6 V VCC.
• Includes Ioff and power-up 3-state circuitry to support hot-insertion applications without damaging backflow currents.
• Features active bus-hold circuitry on data inputs to maintain valid logic levels and prevent floating buses.

Applications

• Hot-insertion systems requiring safe insertion and removal under power.
• Mixed-voltage bus architectures interfacing 5-V logic with 2.5-V or 3.3-V components.
• High-density data routing where flow-through architecture simplifies printed circuit board layout.

Procurement Notes

Verify the specific ordering suffix VR corresponds to the Thin Very Small-Outline (DGV) package configuration. Confirm that the component status is Obsolete as indicated in the packaging addendum before finalizing procurement plans. Ensure design-in compatibility with existing PCB land patterns for the 56-pin TVSOP footprint.

Selection Notes

Select this component when 18-bit wide data transfer is required with integrated storage capabilities. The ABT technology provides low static power dissipation suitable for battery-operated or power-sensitive designs. Verify that the system requires 5-V tolerant interfaces to accommodate legacy or mixed-signal environments effectively.

Part Context

This device belongs to the SN74ALVTH16601 family of universal bus transceivers manufactured by Texas Instruments. It is part of the ALVTH series designed for 2.5-V and 3.3-V applications. The VR suffix specifically denotes the TVSOP-56 plastic shrink small-outline package variant within this product line.

Replacement Considerations

Public documentation lists SN74ALVTH16601DL and SN74ALVTH16601DLR as obsolete alternatives in different packages. No direct pin-compatible replacements are confirmed in the provided source material.
