SN74ALVTH16601GR

Overview

The SN74ALVTH16601GR is an 18-bit universal bus transceiver utilizing Advanced BiCMOS technology. It supports 2.5-V and 3.3-V VCC operation with TTL interface capability for 5-V systems. The device integrates D-type latches and flip-flops, enabling transparent, latched, clocked, or clock-enabled data modes. It features high-drive outputs of –24/24 mA at 2.5 V and –32/64 mA at 3.3 V. Operating temperatures range from –40°C to +85°C.

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 by providing a TTL interface to 5-V system environments while operating at lower voltages.
• Includes active bus-hold circuitry on data inputs to maintain valid logic levels without external pullup or pulldown resistors.
• Features Ioff and power-up 3-state support to prevent damaging current backflow and driver conflicts during hot insertion.

Applications

• Hot-insertion applications requiring controlled output states during power transitions
• Mixed-voltage system interfaces connecting 5-V logic to 2.5-V or 3.3-V buses
• High-density printed circuit board layouts utilizing flow-through architecture

Procurement Notes

Verify the specific package suffix against the orderable part list. The 'GR' designation corresponds to the Thin Very Small-Outline (DGV) package. Confirm that the required temperature range matches the SN74 variant (-40°C to 85°C) rather than the SN54 military grade. Ensure all unused control inputs are tied to VCC or GND for proper operation.

Selection Notes

Select this component when 18-bit wide data transfer is required with integrated storage capabilities. The ALVTH series is suitable for designs needing high drive strength and mixed-signal voltage translation. Verify that the application environment does not exceed the absolute maximum ratings for input or output voltages.
