SN54S174J

Flip Flops Overview

The SN54S174J is a military-grade Hex D-type flip-flop integrated circuit manufactured by Texas Instruments. It features six independent positive-edge-triggered D-type flip-flops with a master clear input, providing non-inverting outputs. The device utilizes Schottky transistor technology for high-speed switching capabilities and includes pull-up resistors on inputs to ensure defined logic states when disconnected. Designed for robust performance in demanding environments, it operates within an extended temperature range of -55°C to +125°C. The component is housed in a ceramic dual in-line package (CDIP) with 16 pins, suitable for hermetic sealing and reliable operation in aerospace or defense applications requiring strict environmental compliance.

Flip Flops Procurement Notes

Verify the specific suffix 'J' corresponds to the ceramic CDIP package variant rather than plastic alternatives. Confirm that the procurement source provides traceable documentation for military-grade qualification standards. Ensure compatibility with existing board layouts designed for dual in-line packages. Check for RoHS exemptions if required by current assembly regulations. Validate supply chain authenticity through authorized distributors to prevent counterfeit components.

Flip Flops Selection Notes

Select this component when high-speed logic operations are required alongside military environmental specifications. The Schottky technology offers faster propagation delays compared to standard LS series devices. Consider the ceramic package for superior thermal stability and hermetic sealing needs. Evaluate power consumption requirements as S-series devices typically draw higher currents than low-power variants. Ensure the design accommodates the specific pinout and electrical characteristics defined in the official datasheet.

Flip Flops Part Context

This part belongs to the Texas Instruments 54Sxx family, representing military-grade Schottky logic devices. The 54 prefix denotes the extended temperature range capability essential for harsh environments. As a member of the 74174 functional group, it provides hex D-flip-flop functionality. The J suffix specifically identifies the ceramic dual in-line package construction, distinguishing it from plastic or other package types within the same logical family.

Flip Flops Replacement Considerations

SN54S174N: Pin-compatible alternative in a different package style. SN54ALS174J: Lower power consumption variant with similar functionality but different electrical characteristics. SN54LS174J: Slower speed option with reduced power usage. Verify voltage levels and drive strengths before substituting.
