CD74ACT175M

Overview

The CD74ACT175M is a high-speed CMOS logic quad D-type flip-flop with reset, manufactured by Texas Instruments. It operates within an extended temperature range of -55°C to +125°C and utilizes a 16-pin SOIC-N package for surface-mount installation. The device features TTL-compatible inputs and CMOS outputs, supporting a supply voltage range from 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 11.5 ns, a maximum low-level output current of 24 mA, and a maximum high-level output current of -24 mA.

Feature Summary

• Integrates four independent D-type flip-flops with asynchronous reset functionality within a single integrated circuit.
• Provides TTL-compatible input thresholds to ensure seamless interface compatibility with standard digital logic families.
• Delivers robust drive capability through specified high and low-level output currents suitable for direct load driving.

Applications

• Parallel data storage registers in digital signal processing systems
• Shift register configurations for serial-to-parallel data conversion
• State machine implementation in control logic circuits

Procurement Notes

Verify the specific suffix 'M' corresponds to the SOIC-N surface-mount package variant rather than the PDIP through-hole version. Confirm that the operating environment remains within the specified -55°C to +125°C thermal limits. Ensure power supply stability stays between 4.5 V and 5.5 V to maintain timing integrity. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a compact surface-mount solution is required for quad D-type flip-flop applications. The ACT series offers faster switching speeds compared to HC variants while maintaining CMOS power efficiency. Consider the 16-pin SOIC-N footprint constraints during PCB layout design. Verify input compatibility requirements against the TTL threshold characteristics provided in the datasheet.

Part Context

This part belongs to the Texas Instruments CD74ACT family of advanced CMOS logic devices. It serves as a functional equivalent to other industry-standard quad D-type flip-flops but is optimized for higher speed performance. The device is designed for use in complex digital systems requiring reliable data storage and transfer operations under varying industrial conditions.
