CD74ACT297M

Overview

The CD74ACT297M is a Phase Lock Loop (PLL) integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum frequency of 55MHz. The device is housed in a 16-SOIC package with a width of 0.154 inches (3.90mm). It functions as a single-channel clock generator suitable for surface-mount assembly. The component is designed for industrial temperature ranges, operating reliably between -55°C and 125°C. This PLL IC provides stable frequency synthesis capabilities for digital systems requiring precise clock timing.

Feature Summary

• Integrates phase lock loop functionality for clock synchronization
• Supports surface-mount technology for automated assembly
• Operates across extended industrial temperature ranges

Applications

• Clock generation in digital communication systems
• Frequency synthesis for microprocessor-based designs
• Timing reference circuits in industrial control equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and temperature grade. Confirm that the 16-SOIC footprint matches the target PCB design. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a 55MHz maximum frequency PLL is required within the 74ACT logic family. Ensure the design accommodates the 4.5V to 5.5V supply voltage constraint. Verify that the 16-pin SOIC package dimensions fit the available board space and thermal requirements for the intended operating environment.

Part Context

This part belongs to the Texas Instruments 74ACT series of high-speed CMOS logic devices. The CD74ACT297M specifically addresses phase-locked loop applications within this family. It complements other clock distribution and timing components offered by the manufacturer for complete system synchronization solutions.

Replacement Considerations

Check for direct cross-references from other manufacturers offering equivalent 16-SOIC PLL ICs with matching 55MHz specifications and 74ACT compatibility. Verify pin-to-pin compatibility if substituting with similar parts from different vendors.
