SN74ABT841ADWG4

Latches Overview

The SN74ABT841ADWG4 is a 10-bit bus-interface D-type latch with 3-state outputs manufactured by Texas Instruments. It utilizes state-of-the-art EPIC-IIB BiCMOS design to significantly reduce power dissipation while providing high-drive outputs capable of driving highly capacitive or low-impedance loads. The device features buffered output-enable inputs and maintains a high-impedance state during power-up and power-down. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to 85°C.

Latches Feature Summary

• Utilizes state-of-the-art EPIC-IIB BiCMOS design for reduced power dissipation
• Provides high-drive outputs suitable for driving highly capacitive or low-impedance loads
• Maintains a high-impedance state during power-up and power-down sequences
• Features buffered output-enable inputs to control logic states or high-impedance conditions

Latches Applications

• Implementing buffer registers
• Designing I/O ports
• Creating bidirectional bus drivers
• Constructing working registers

Latches Procurement Notes

Verify the specific ordering suffix 'G4' corresponds to lead-free packaging and RoHS compliance as indicated in TI documentation. Confirm that the DW package designation matches the required SOIC footprint and pin count for your PCB layout. Ensure the component status is listed as active production before finalizing procurement plans.

Latches Selection Notes

Select this component when a 10-bit latch configuration is required for bus interface applications. The ABT series offers higher drive strength compared to standard logic families, making it appropriate for low-impedance loads. Consider the 24-pin SOIC package dimensions and thermal characteristics if space or heat dissipation are critical constraints in the design.

Latches Part Context

This part belongs to the SN54ABT841/SN74ABT841A family of 10-bit bus-interface D-type latches. The SN74 variant is characterized for commercial temperatures (-40°C to 85°C), whereas the SN54 version covers the full military range. The G4 suffix typically denotes environmental compliance, specifically lead-free materials and RoHS adherence.

Latches Replacement Considerations

SN74ABT841ADW is a direct equivalent without the G4 suffix but shares identical electrical specifications and functionality.
