SNJ54ACT74J

Flip Flops Overview

The SNJ54ACT74J is a dual positive-edge-triggered D-type flip-flop manufactured by Texas Instruments. It features independent clear and preset inputs for each of the two circuits, providing flexible state control. The device utilizes a ceramic flatpack (CFP) package with 14 pins, designed for through-hole mounting. It operates within a supply voltage range of 2 V to 6 V and supports an extended industrial temperature range from -55°C to +125°C. This component belongs to the ACT logic series, ensuring compatibility with TTL input levels while offering CMOS output characteristics.

Flip Flops Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or factory special order constraints. Confirm that the ceramic flatpack package matches your PCB footprint requirements. Ensure that the extended temperature range aligns with your system's operational environment specifications before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when dual edge-triggered storage with direct clear and preset controls is required in a ruggedized form factor. The ACT series offers speed and drive strength suitable for general-purpose logic applications. Consider the CFP package size and through-hole mounting method during mechanical design integration to ensure proper board layout compatibility.

Flip Flops Part Context

This device is part of the SN54ACT family, which provides advanced CMOS technology for high-speed digital applications. The SNJ prefix indicates a military-grade variant with specific screening and reliability standards. It complements other logic components like the SNJ54ACT374J octal flip-flop by offering a compact dual-channel solution for sequential logic design.

Flip Flops Replacement Considerations

Consider the SNJ54ACT74W as a potential substitute if available, noting the identical functional specification but potentially different packaging. Verify pinout compatibility and electrical parameters against the original datasheet before implementation.
