CD74ACT109M96

Overview

The CD74ACT109M96 is a high-speed CMOS logic integrated circuit manufactured by Texas Instruments, belonging to the 74ACT series. It functions as a dual JK-type flip-flop with T-mode capability, packaged in a 16-pin SOIC (Small Outline Integrated Circuit) format for surface mount technology. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 60 MHz. It features positive-edge triggering, complementary outputs, and built-in preset and reset functions. The component is designed for robust performance across an extended industrial temperature range from -55°C to +125°C, ensuring reliable operation in demanding digital logic applications.

Procurement Notes

Verify the specific suffix M96 against official Texas Instruments documentation to confirm packaging configuration and reel specifications. Ensure compatibility with standard 74ACT logic voltage levels during integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability. Confirm that the selected package variant meets the required PCB footprint and thermal dissipation constraints for the target application design.

Selection Notes

Select this component when designing circuits requiring dual JK or T flip-flops with high-speed switching capabilities. The 74ACT series offers faster propagation delays compared to standard HC logic while maintaining CMOS power efficiency. Consider the 16-SOIC package dimensions for board space limitations. Verify that the system power supply strictly adheres to the 4.5 V to 5.5 V operational range to ensure signal integrity and prevent functional degradation under varying load conditions.

Part Context

This device is part of the broader Texas Instruments 74ACT logic family, which bridges the performance gap between older TTL standards and modern low-voltage CMOS technologies. The ACT series is characterized by balanced rise and fall times, making it suitable for high-frequency digital systems. The CD74ACT109 specifically addresses applications needing multiple independent flip-flops in a compact surface-mount package, serving as a fundamental building block for complex sequential logic designs in industrial and consumer electronics.

Replacement Considerations

Compatible substitutes include the CD74HC109M96 for lower-speed applications and the CD74HCT109M96 for TTL-compatible input interfaces. Alternative manufacturers may offer equivalent parts such as the SN74ACT109N, though pinout and electrical characteristics must be verified against the original datasheet before implementation.
