74HC175D

Overview

The Toshiba Semiconductor and Storage 74HC175D is a quad D-type flip-flop belonging to the 74HC CMOS logic IC series. It features four independent D-type flip-flops with positive-edge triggering within a single integrated circuit. The device operates on a supply voltage range of 2 V to 6 V and utilizes an SOIC-16 surface-mount package. Key electrical specifications include a maximum clock frequency of 63 MHz, a propagation delay of 16 ns at 5 V, and output drive currents of ±5.2 mA. It supports a wide operating temperature range from -40 °C to +125 °C.

Feature Summary

• Contains four independent positive-edge triggered D-type flip-flops for parallel data storage
• CMOS technology ensures low power consumption and high noise immunity
• Wide operating voltage range compatible with standard digital logic systems
• High-speed performance suitable for synchronous digital applications

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in digital systems
• General-purpose memory storage elements
• Timing and synchronization logic modules

Procurement Notes

Verify the specific manufacturer suffix and revision status when sourcing, as part number revisions may occur without functional changes. Confirm RoHS compliance and moisture sensitivity levels against current project requirements. Ensure the SOIC-16 package dimensions match the PCB footprint design. Cross-reference datasheet electrical characteristics with system timing constraints before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring multiple synchronized storage elements in a compact surface-mount form factor. The HC series offers balanced speed and power consumption compared to other logic families. Consider the 6 V maximum rating when designing for higher voltage environments. Verify that the input logic levels are compatible with the driving source across the entire operating voltage range.

Part Context

This component is part of the extensive 74HC family of high-speed CMOS logic devices manufactured by Toshiba Semiconductor and Storage. The 74HC175 specifically addresses the need for multi-bit storage within a single package, reducing board space compared to discrete flip-flops. It serves as a fundamental building block for complex sequential logic circuits in consumer electronics and industrial control systems.

Replacement Considerations

The 74HC175D(BJ) is listed as an alias or previous part number variant for this component. Other manufacturers produce pin-compatible equivalents such as the NXP 74HCT175, though HCT logic requires different input voltage thresholds. Verify package compatibility and electrical specifications when substituting with parts from different vendors.
