CD74ACT175M

Overview

The CD74ACT175M is a D-type flip-flop integrated circuit manufactured by Harris Corporation. It contains one element with four-bit storage capacity, utilizing positive edge triggering for data capture. The device operates within a supply voltage range of 2V to 6V and supports clock frequencies up to 114 MHz. It features complementary outputs and accepts 3.3V CMOS inputs as valid high levels (VIH ≥ 2.0V), allowing direct connection to 3.3V logic systems. The component is housed in a 16-SOIC package with dimensions of 0.154 inches (3.90mm) width.

Feature Summary

• Positive edge triggered D-type operation for reliable data synchronization
• Complementary output configuration providing both true and inverted signals
• Direct compatibility with 3.3V logic systems through specified input threshold levels

Applications

• Synchronous digital data storage circuits
• Shift register implementations requiring parallel load capabilities
• Timing control logic in mixed-voltage system interfaces

Procurement Notes

Verify the specific manufacturer source when sourcing this component, as Harris Corporation's semiconductor assets have undergone various acquisitions and reorganizations. Confirm that the received unit matches the original Harris Corporation specifications rather than subsequent licensee versions, which may differ in electrical characteristics or pinout definitions. Ensure the package type corresponds exactly to the 16-SOIC form factor required for your design integration.

Selection Notes

Select the CD74ACT175M when designing systems requiring high-speed synchronous data latching with mixed 5V and 3.3V logic interfacing. Its ACT series technology offers faster switching speeds compared to standard HC or HCT counterparts. Consider the complementary output feature if signal inversion hardware is needed elsewhere in the circuit. Validate that the operating temperature range meets your environmental requirements before finalizing the component choice.

Part Context

This component belongs to the CD74ACT family of advanced CMOS logic devices from Harris Corporation. The ACT series was designed to provide higher performance and lower power consumption compared to earlier AC and AHC families. As a D-type flip-flop, it serves as a fundamental building block for sequential logic circuits, enabling state retention and data movement in complex digital architectures.
