SN74LVC646ADW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC646ADW is an octal bus transceiver and register featuring 3-state outputs, manufactured by Texas Instruments. It operates within a voltage range of 1.65 V to 3.6 V and accepts input voltages up to 5.5 V. The device utilizes a 24-SOIC package with a maximum propagation delay of 7.4 ns at 3.3 V. Designed for multiplexed data transmission, it integrates D-type flip-flops and control circuitry directly from the inputs.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports direct multiplexed transmission of data via integrated D-type flip-flops and control circuitry
• Provides 3-state outputs for effective bus line management and isolation
• Accepts 5.5 V input voltages while operating at lower supply voltages down to 1.65 V

Buffers, Drivers, Receivers, Transceivers Applications

• Multiplexed data transmission systems
• Memory bus architectures requiring bidirectional data flow
• I/O port expansion in low-voltage digital circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the 24-SOIC package variant when sourcing. Confirm that the required operating temperature range aligns with the commercial grade specifications (-40°C to 85°C). Ensure input voltage levels do not exceed the 5.5 V absolute maximum rating to prevent device damage during system integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed octal data transfer with mixed voltage compatibility. The 5.5 V tolerant inputs allow interfacing with legacy 5 V logic without level shifters. Consider the 24-SOIC footprint for PCB layout constraints and verify power supply stability within the 1.65 V to 3.6 V range for optimal performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the LVC (Low Voltage CMOS) family, designed for high-speed operation with low power consumption. The SN74LVC646A series provides robust performance for modern embedded systems. The 'D' suffix indicates the SOIC package type, distinguishing it from tape-and-reel or other package variants like PW or DBR.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVC646ADBR is a verified alternative offering identical electrical characteristics and functionality in a different surface-mount package configuration.
