CD74HC175E

Overview

The CD74HC175E is a high-speed CMOS quad D-type flip-flop manufactured by Harris Corporation. It features four independent positive-edge-triggered D flip-flops with complementary outputs and an active-low asynchronous reset input. The device operates within a supply voltage range of 2V to 6V, supporting a maximum operating frequency of 20MHz. Key electrical parameters include a propagation delay of 220ns, a load capacitance of 50pF, and a maximum output current of 4mA. It functions reliably across an extended temperature range from -40°C to 85°C.

Feature Summary

• Contains four independent positive-edge-triggered D flip-flops
• Provides complementary outputs for each flip-flop stage
• Features an active-low asynchronous reset input for immediate clearing
• Utilizes standard HC/UH series CMOS logic technology

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations in digital systems
• General-purpose storage elements in microprocessor interfaces
• Timing and synchronization logic applications

Procurement Notes

Verify the manufacturer designation on the component marking to confirm Harris Corporation origin rather than Texas Instruments production. Ensure the package type matches the required DIP-16 specification. Check for RoHS compliance status as older Harris manufacturing runs may not meet current environmental standards. Confirm the specific suffix indicates the correct temperature grade and pin configuration for your application requirements.

Selection Notes

Select this component when complementary outputs are required for each bit position in a quadruple flip-flop arrangement. Choose the HC series for general high-speed CMOS applications requiring compatibility with standard logic families. Consider the 2V to 6V supply range flexibility for varying system voltages. Verify that the asynchronous reset functionality meets the system initialization needs compared to synchronous alternatives.

Part Context

This part belongs to the 74HC175 family of quad D-type flip-flops. It is functionally equivalent to other manufacturers' 74HC175 devices but carries the Harris Corporation branding. The device represents a standard solution for multi-bit data storage in legacy and industrial electronic designs utilizing CMOS logic technology.
