CD74ACT174M

Overview

The CD74ACT174M is a hex D-type flip-flop manufactured by Texas Instruments, belonging to the ACT logic series. It features six independent positive-edge-triggered D-type flip-flops with a master reset input in a 16-pin SOIC package. The device operates within a supply voltage range of 1.5V to 5.5V and supports a maximum clock frequency of 95 MHz. Key electrical parameters include a typical propagation delay of 13.5ns at 5V with 50pF load, output drive currents of ±24mA, and a static current consumption of 8µA. It functions across an industrial temperature range of -55°C to 125°C.

Feature Summary

• Contains six independent positive-edge-triggered D-type flip-flops
• Features a common master reset input for synchronous clearing
• Provides high-current CMOS outputs capable of driving standard CMOS and TTL loads
• Operates over a wide supply voltage range from 1.5V to 5.5V

Applications

• Parallel data storage and buffering in digital systems
• Shift register construction for serial-to-parallel conversion
• Timing delay elements in pulse generation circuits
• State machine implementation in control logic

Procurement Notes

Verify the specific manufacturer designation, as the part number indicates Texas Instruments origin despite the query brand. Confirm the package type matches the required 16-SOIC footprint. Check RoHS compliance status if environmental regulations apply to the end product. Ensure the operating temperature range meets the system requirements given the -55°C to 125°C specification. Validate that the ACT series logic levels are compatible with the surrounding circuitry voltage domains.

Selection Notes

Select this component when requiring a hex D-type flip-flop with high-speed performance and wide voltage tolerance. The ACT series offers faster switching speeds compared to standard AC or HC families while maintaining low power consumption. Consider the 16-SOIC package for surface-mount assembly needs. Evaluate the 95 MHz maximum clock frequency against the system timing constraints. Ensure the ±24mA output drive capability suffices for the connected load capacitance and fan-out requirements.

Part Context

This component is part of the Texas Instruments 74ACT family of high-speed CMOS logic devices. It serves as a direct functional equivalent to other hex D-type flip-flops like the 74AC174, but with optimized speed and drive characteristics typical of the ACT line. The device is designed for applications requiring reliable data latching and high-frequency operation in mixed-signal environments.
