CD74AC174M96E4

Overview

The CD74AC174M96E4 is a hex D-type flip-flop from Texas Instruments' AC logic series, housed in a 16-SOIC package. It features six independent positive-edge-triggered circuits with asynchronous master reset inputs. The device operates within a supply voltage range of 1.5V to 5.5V and supports a maximum clock frequency of 80MHz at nominal supply. Propagation delay is specified at 13.5ns under standard conditions. It includes high-current outputs capable of sourcing and sinking 24mA, ensuring robust signal integrity across the -55°C to +125°C operating temperature range.

Feature Summary

• Integrates six independent D-type flip-flops with positive-edge triggering for parallel data storage
• Provides asynchronous master reset functionality to initialize all outputs simultaneously
• Delivers high-drive output capability with 24mA source and sink current capacity
• Supports wide supply voltage operation from 1.5V to 5.5V for flexible system integration

Applications

• Parallel-to-serial and serial-to-parallel data conversion interfaces
• General-purpose register stages in digital processing systems
• Timing alignment and synchronization buffers for clock domains
• State holding elements in finite state machine implementations

Procurement Notes

Verify the complete part number including the E4 suffix to confirm lead-free compliance and specific tape-and-reel packaging configuration. Ensure the procurement channel sources directly from authorized distributors or Texas Instruments to guarantee authenticity. Cross-reference the datasheet revision date against your design requirements to confirm parameter stability. Confirm that the SOIC-16 package dimensions match your PCB footprint specifications before finalizing orders.

Selection Notes

Select this component when designing systems requiring multiple synchronized storage elements with fast switching speeds. The AC series offers superior performance compared to standard HC logic while maintaining pin compatibility. Consider the 24mA output drive strength if interfacing with heavy capacitive loads or long traces. Verify that the 1.5V minimum supply voltage aligns with your system's power rail availability and noise margins.

Part Context

This device belongs to the Texas Instruments 74AC family of high-speed CMOS logic devices. The 74AC series provides faster propagation delays than the legacy 74LS series while consuming lower power. The CD74 variant indicates commercial temperature grade operation. The M96 suffix typically denotes specific packaging and handling characteristics defined by the manufacturer for surface-mount assembly processes.

Replacement Considerations

The CD74AC174M96 is a direct functional equivalent and may serve as a substitute. For non-lead-free requirements, check for variants without the E4 suffix. Upgrading to the 74ACT series offers improved noise immunity but requires strict adherence to voltage level constraints.
