CD74ACT112M

Overview

The CD74ACT112M is a dual JK-type flip-flop manufactured by Texas Instruments, belonging to the SN74ACT logic series. It features negative-edge triggering with set and reset inputs. The device operates within a supply voltage range of 1.5 V to 5.5 V and supports a maximum clock frequency of 100 MHz. Key electrical parameters include a propagation delay of 10.3 ns at 5 V with 50 pF load, output currents of ±24 mA, and static current of 4 µA. It is housed in a 16-SOIC package and functions across an extended temperature range of -55°C to +125°C.

Feature Summary

• Dual JK-type flip-flops with negative-edge triggering for precise data synchronization
• Integrated set and reset inputs for direct control of output states
• High-speed operation supporting up to 100 MHz clock frequencies
• Wide operating voltage range from 1.5 V to 5.5 V for flexible power integration

Applications

• Parallel-to-serial and serial-to-parallel data conversion circuits
• Frequency division and counting applications in digital systems
• Shift register construction for data storage and movement
• State machine implementation in programmable logic designs

Procurement Notes

Verify the specific suffix (e.g., M96) against the manufacturer's official datasheet to confirm package dimensions and pinout compatibility. Ensure the ordered variant matches the required operating temperature range and voltage specifications for your application environment. Cross-reference the ordering number with Texas Instruments documentation to avoid confusion with similar ACT series components.

Selection Notes

Select this component when dual independent JK flip-flops with set/reset functionality are required in a compact surface-mount package. The wide voltage range allows compatibility with both 3.3 V and 5 V logic systems. Consider the 10.3 ns propagation delay and 100 MHz speed for high-frequency timing requirements. Ensure the 16-SOIC footprint fits the PCB layout constraints compared to through-hole alternatives.

Part Context

The CD74ACT112M belongs to the Texas Instruments SN74ACT family, which combines advanced CMOS technology with TTL-compatible inputs. This series offers faster switching speeds than standard AC devices while maintaining low power consumption. The ACT family is designed for high-performance digital applications requiring reliable logic operations across industrial and commercial temperature ranges.
