QS74FCT845ATSO

Latches Overview

The QS74FCT845ATSO is an octal bus transceiver from the 74FCT series manufactured by Quality Semiconductor. It features non-inverting logic with three-state outputs and operates on a single 5V supply voltage. The device supports surface-mount installation in a 20-pin SSOP package. It provides high-speed data transfer capabilities suitable for memory and microcontroller-based systems, ensuring signal integrity through controlled drive strengths and low input capacitance characteristics typical of the FCT logic family.

Latches Feature Summary

• Octal bus transceiver architecture for bidirectional data flow
• Three-state outputs to prevent bus contention
• Non-inverting logic function for direct signal transmission
• Compatible with standard 5V CMOS logic levels

Latches Applications

• Memory buffer applications in computer systems
• Clock drivers and distribution networks
• Bus-oriented communications interfaces
• Control signaling between microprocessors and peripherals

Latches Procurement Notes

Verify the manufacturer designation as Quality Semiconductor or its successor entities, as corporate acquisitions may affect part sourcing. Confirm the specific suffix 'TSO' corresponds to the required 20-SSOP package variant. Ensure compliance with current RoHS directives if environmental regulations apply to your deployment. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

Latches Selection Notes

Select this component when an octal width is required for bus isolation or buffering. The 74FCT technology offers a balance between speed and power consumption compared to older TTL families. Verify that the operating voltage range matches the system's 5V rail. Consider the thermal performance of the SSOP package for the intended enclosure environment.

Latches Part Context

This part belongs to the 74FCT logic family, which bridges the performance gap between Fast TTL and Fast CMOS technologies. Quality Semiconductor was a notable producer of these components before industry consolidation. The 845 designation typically indicates an octal transceiver configuration within this specific product line hierarchy.

Latches Replacement Considerations

Check for equivalents from Texas Instruments or ON Semiconductor under the 74FCT845 designation. Verify pin compatibility and electrical specifications before substitution. Note that newer generations may have updated packaging options or improved switching characteristics.
