QS74FCT2273TS0

Flip Flops Overview

The QS74FCT2273TS0 is an 8-bit D flip-flop belonging to the FCT logic series, manufactured by Quality Semiconductor. It features positive edge triggering and true outputs implemented in CMOS technology. The component is housed in a 20-pin Small Outline package (QSOP/SSOP) with a plastic body. Electrical specifications include a load capacitance of 50 pF and an operating temperature range from -40 °C to +85 °C. The device supports series-resistor output characteristics and operates within standard industrial voltage parameters.

Flip Flops Feature Summary

• Provides eight independent D-type storage elements triggered on the positive clock edge
• Delivers non-inverted true outputs for direct signal interfacing
• Utilizes CMOS architecture for low power consumption and high noise immunity
• Integrates series resistors at outputs to manage signal integrity

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose register arrays in digital systems
• Timing synchronization and delay line implementations
• Data latch buffers in microprocessor interfaces

Flip Flops Procurement Notes

Verify the specific package variant against the datasheet, as suffixes may indicate minor physical differences without altering function. Confirm lead times and availability directly with authorized distributors or the manufacturer. Ensure the procurement channel provides valid traceability documentation. Cross-reference the ordering part number with the official Quality Semiconductor catalog to avoid substitution errors during assembly.

Flip Flops Selection Notes

Select this component when an 8-bit synchronous storage solution with true outputs is required. The FCT series offers compatibility with Fast CMOS logic families, facilitating mixed-technology designs. Consider the 20-pin form factor for board space constraints. Verify that the positive edge-triggering behavior aligns with the system clock timing requirements and that the industrial temperature range meets environmental conditions.

Flip Flops Part Context

This part belongs to the broader FCT logic family, which bridges the performance gap between standard TTL and CMOS technologies. Quality Semiconductor produces this series to provide high-speed switching with CMOS power efficiency. The QS74FCT2273TS0 specifically addresses applications requiring parallel data retention with simple serial or parallel readout capabilities in embedded control systems.

Flip Flops Replacement Considerations

The PI74FCT2273CTQX serves as a functional equivalent from Pericom/Diodes Incorporated. Both parts share identical logical functionality, pin configurations, and electrical characteristics. Substitution requires verification of package dimensions and thermal specifications to ensure mechanical compatibility.
