SN74ALS845NT3

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS845NT3 is an AS series, 8-bit bus driver with true outputs housed in a PDIP-24 package. It features triple output enable capabilities and includes clear and preset functions. The device supports power-off disabled outputs to permit live insertion. It operates within a temperature range of 0°C to 70°C. Maximum supply current is 85 mA. Load capacitance is specified at 50 pF.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides three-state output control for bidirectional data transfer
• Supports live insertion via power-off output disable functionality
• Integrates clear and preset inputs for direct state management

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and register systems
• Bidirectional data transmission between buses
• Clock drivers and buffer circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify RoHS non-compliance status before integration into regulated assemblies. Confirm the presence of the NT3 suffix indicates tape-and-reel packaging rather than tube. Ensure the specific date code meets traceability requirements for your manufacturing process. Validate that the PDIP-24 footprint matches your PCB design constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed 8-bit data transfer is required with tri-state isolation. The ALS series offers improved speed-power product compared to standard TTL. Consider the triple enable feature for complex bus arbitration schemes. Verify voltage levels match the system logic family requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74AS/ALS logic family, designed for high-speed applications. The SN74ALS845 variant specifically provides 8-bit buffering with true output polarity. It serves as a bridge between different logic domains or bus segments requiring controlled signal directionality.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74ALS845N or SN74ALS845DW as potential pin-compatible alternatives from the same manufacturer. Verify electrical specifications and package dimensions before substitution.
