CD74ACT175E

Overview

The CD74ACT175E is a quad D flip-flop utilizing Harris Advanced CMOS Logic technology. It features positive edge triggering and complementary outputs for each of the four bits. The device operates within a supply voltage range of 4.5V to 5.5V, with a quiescent current of 8 µA. It supports a maximum operating frequency of 20 MHz at nominal supply and exhibits a propagation delay of 220 ns. The component provides high output drive capability with currents of 4 mA and functions reliably across an extended temperature range from -40°C to 85°C.

Feature Summary

• Quad D flip-flop architecture with positive edge triggering
• Complementary output configuration for all four bits
• Advanced CMOS logic technology for high-speed operation
• Extended industrial temperature range capability

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Timing control and synchronization systems
• Digital state storage applications

Procurement Notes

Verify the manufacturer designation on the component marking to confirm Harris Corporation origin. Ensure the package type matches the required DIP-16 specification for your PCB layout. Cross-reference the datasheet revision to confirm electrical characteristics align with your system requirements. Confirm that the supply voltage constraints are strictly maintained during operation.

Selection Notes

Select this component when complementary outputs are required for differential signaling or specific logic interfacing needs. The ACT series offers superior speed compared to standard HC/UH variants while maintaining CMOS compatibility. Consider the 4 mA output drive strength for moderate load conditions. Verify that the 4.5V minimum supply voltage requirement fits within your power rail design.

Part Context

This part belongs to the CD74ACT175 family of quad D flip-flops. It shares functional similarities with other ACT series logic devices but is distinct in its four-bit configuration and complementary output structure. The device represents Harris Corporation's implementation of advanced CMOS technology for digital logic applications requiring reliable state retention.

Replacement Considerations

The CD74ACT175E serves as a direct substitute for the 74ACT175PC. Both components share identical base product functionality and electrical characteristics. Ensure pinout compatibility and package dimensions match before replacement.
