SN74LVT16501DGGR

Overview

The SN74LVT16501DGGR is a 3.3-V ABT 18-bit universal bus transceiver with 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and supports mixed-mode signal operation, allowing 5-V input and output voltages with a 3.3-V VCC. The device features active bus-hold circuitry on data inputs and utilizes Advanced BiCMOS technology for low-static power dissipation. It is housed in a 56-pin Thin Shrink Small-Outline (DGG) package.

Feature Summary

• Supports mixed-mode signal operation with 5-V tolerant I/Os while operating at 3.3 V
• Combines D-type latches and flip-flops for transparent, latched, or clocked modes
• Active bus-hold circuitry eliminates the need for external pullup/pulldown resistors

Applications

• High-density memory mapping
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify that the component matches the SN74LVT16501DGGR designation and originates from Texas Instruments. Confirm the package type is TSSOP (DGG) with 56 pins. Ensure the part meets RoHS compliance standards and check the moisture sensitivity level rating before assembly. Validate the operating temperature range against system requirements.

Selection Notes

Select this component when an 18-bit wide bus interface is required with mixed-voltage compatibility. The ABT technology provides high-speed performance suitable for demanding applications. Consider the flow-through architecture for optimized PCB layout. Verify that the 3.3-V supply voltage aligns with the target system environment.

Part Context

This device belongs to the Widebus family of Texas Instruments logic products. It is designed for low-voltage 3.3-V operations but maintains TTL interface capabilities. The SN74LVT16501 complements other members of the family by providing extensive pin count functionality in a compact surface-mount package.
