SNJ54F109W

Flip Flops Overview

The SNJ54F109W is a dual J-K positive-edge-triggered flip-flop from the Texas Instruments F/FAST logic series. It features independent preset and clear inputs for direct state control. The device operates within a supply voltage range of 4.5 V to 5.5 V. It utilizes a 16-lead ceramic flatpack (CFP) package designed for military-grade reliability. The component supports complementary outputs and includes an inverted K input configuration. It is rated for operation across an extended temperature range of -55°C to +125°C, ensuring stability in demanding environments.

Flip Flops Procurement Notes

Verify that the part number suffix 'W' corresponds to the specific 16-lead ceramic flatpack package variant. Confirm that the manufacturer source is authorized to supply military-specification components. Ensure compliance with required environmental testing standards for the intended application environment. Check for any specific handling requirements associated with ceramic packages.

Flip Flops Selection Notes

Select this component when military-grade temperature tolerance and radiation hardness are required. The F/FAST series offers higher speed than LS variants but consumes more power. Consider the physical size constraints of the 16-lead CFP package during PCB layout. Evaluate system power budget against the typical current consumption of the F series logic family.

Flip Flops Part Context

This device belongs to the SN54xx series, which denotes military-grade specifications compared to the commercial SN74xx series. The F/FAST family provides faster switching speeds suitable for high-frequency applications. The SNJ54F109W serves as a fundamental building block for complex sequential logic designs requiring robust performance under extreme conditions.

Flip Flops Replacement Considerations

SNJ54LS109AW: Offers lower power consumption but reduced speed; requires voltage level verification.
