CD74HCT175EE4

Overview

The CD74HCT175EE4 is a quad D-type flip-flop manufactured by Texas Instruments using silicon-gate CMOS technology. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 25 MHz. The device features four independent D-type flip-flops with positive-edge triggering, providing both true and complementary outputs for each stage. It includes an asynchronous master reset input that forces all outputs to a low state independently of the clock signal. Designed for through-hole mounting, it utilizes a 16-pin DIP package.

Feature Summary

• Provides four independent D-type flip-flops with positive-edge triggering for data storage applications
• Features an asynchronous master reset input that overrides clock signals to clear outputs
• Delivers both true and complementary outputs for each flip-flop stage
• Ensures compatibility with standard TTL logic levels through HCT series design

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for digital signal processing
• General-purpose memory storage elements in digital systems
• Timing and synchronization logic in control systems

Procurement Notes

Verify the specific suffix EE4 indicates compliance with environmental standards and packaging requirements when sourcing. Confirm the package type matches the intended PCB footprint, as variations exist between surface mount and through-hole options. Ensure the supplier provides documentation confirming the active status of this component variant, as availability may fluctuate across different distribution channels.

Selection Notes

Select this component when a quad D-type flip-flop with asynchronous reset functionality is required in a through-hole design. It is suitable for applications needing interface compatibility with LSTTL logic families while maintaining CMOS power efficiency. Consider the 25 MHz maximum clock frequency limit when designing high-speed timing circuits to ensure reliable operation within specified electrical parameters.

Part Context

This part belongs to the Texas Instruments 74HCT series of logic integrated circuits, which are designed to bridge the gap between high-speed CMOS and Low-power Schottky TTL technologies. The 74HCT175 specifically functions as a quad D-type flip-flop, offering a compact solution for storing four bits of data. It is part of a broader family of logic devices used extensively in digital electronics for data handling and control operations.

Replacement Considerations

The CD74HCT175E is a direct equivalent without the E4 suffix, offering identical electrical characteristics and pinout configuration. Both variants function as quad D-type flip-flops with asynchronous reset inputs. Verify that any substitute maintains the same DIP-16 through-hole package specification to ensure mechanical compatibility with existing board layouts.
