74ACT16651DLR

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74ACT16651DLR is a 16-bit bus transceiver and register with 3-state outputs, utilizing the Widebus family architecture. It consists of D-type flip-flops arranged for multiplexed transmission of data directly from the data bus or internal storage registers. The device supports independent registers and enables for A and B buses, allowing configuration as two 8-bit transceivers or one 16-bit transceiver. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The component is packaged in a 56-pin SSOP (DL) format.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Multiplexed real-time and stored data transmission via independent select-control inputs
• Distributed VCC and GND pin configurations to minimize high-speed switching noise
• Flow-through architecture optimized for PCB layout efficiency
• Elimination of typical decoding glitches during transitions between stored and real-time data

Buffers, Drivers, Receivers, Transceivers Applications

• Bus management functions requiring simultaneous real-time and registered data paths
• System designs needing independent control over A and B bus directions
• High-density logic applications utilizing Widebus package technology

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Ensure the selected variant matches the required operating temperature range and RoHS compliance status for the intended application environment. Cross-reference the active status and lead finish details provided in the packaging information section.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single integrated solution is required for both bus buffering and data latching across 16 bits. The Widebus package provides higher I/O density compared to standard small-outline packages within the same board area. Consider the distributed power and ground pins if minimizing switching noise is critical for signal integrity in high-speed digital systems.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus family, designed to offer increased functionality without increasing footprint. It utilizes EPIC (Enhanced-Performance Implanted CMOS) technology for improved performance. The 74ACT16651 serves as a complementary counterpart to non-inverting variants, providing inverting data paths for flexible system design requirements.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN54ACT16651 for military temperature range requirements. Verify compatibility with other Widebus family members like the 74ACT16652 for similar functionality with non-inverting paths.
