CD74AC174M

Overview

The CD74AC174M is a hex D-type flip-flop integrated circuit manufactured by Texas Instruments. It features six independent positive-edge-triggered D flip-flops with an asynchronous master reset input. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports data rates up to 95 MHz. It is housed in a 16-SOIC package with a width of 3.90 mm, designed for surface-mount installation across an extended temperature range of -55°C to +125°C.

Feature Summary

• Contains six independent positive-edge-triggered D-type flip-flops
• Includes an asynchronous master reset input for immediate state clearing
• Supports high-speed operation with a maximum clock frequency of 95 MHz
• Provides non-inverting outputs with standard CMOS drive capabilities

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data storage and transfer
• General-purpose digital logic buffering and timing control
• State machine implementation in embedded systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate tape-and-reel packaging versus tube quantities. Review the latest Product Change Notification (PCN) documents for any discontinuance notices or design specification updates prior to finalizing procurement orders.

Selection Notes

Select this component when requiring multiple synchronized storage elements within a single package. Ensure the application voltage remains within the 1.5 V to 5.5 V operational limits. Consider the 16-SOIC footprint constraints during PCB layout. Verify that the required propagation delay characteristics align with system timing requirements for reliable data capture at the specified clock frequencies.

Part Context

This part belongs to the Texas Instruments CD74AC series, which utilizes advanced silicon gate CMOS technology. The AC series offers performance comparable to older LS logic families but with lower power consumption and wider operating voltage ranges. The CD prefix indicates commercial grade temperature specifications, while the 174 designation specifically identifies the hex D-flip-flop function within the broader logic catalog.
