SN74LS174M

Flip Flops Overview

The SN74LS174M is a Hex D Flip-Flop manufactured by Motorola, belonging to the LS (Low-Power Schottky) logic series. It contains six independent positive edge-triggered D-type flip-flops with complementary outputs within a single package. The device features an asynchronous common clear input that simultaneously resets all flip-flops when activated. Designed for high-speed applications, it utilizes the Schottky barrier diode process to minimize propagation delays while maintaining low power consumption. The component is compatible with standard TTL families and includes input clamp diodes to limit high-speed termination effects.

Flip Flops Procurement Notes

Verify the manufacturer origin carefully, as Texas Instruments also produces the SN54/74LS174 variant. Confirm the 'M' suffix indicates the plastic DIP or SOIC package type specific to Motorola's designation. Ensure compatibility with existing TTL logic levels and check for RoHS compliance status if required for modern manufacturing standards. Cross-reference datasheets from NXP or other authorized distributors for accurate pinout and electrical specifications.

Flip Flops Selection Notes

Select this component when a hex configuration of D flip-flops is required without individual clocking per stage. The LS series offers a balance between speed and power dissipation suitable for commercial temperature ranges. Consider the asynchronous clear feature for system initialization needs. Verify voltage supply requirements against the standard 5V TTL operating range. Evaluate package availability and lead times compared to alternative manufacturers offering similar hex flip-flop configurations.

Flip Flops Part Context

This part belongs to the widely used 74LS logic family, known for its robustness and compatibility across various digital systems. Motorola was a primary producer of these components before NXP acquired their semiconductor division. The SN74LS174M represents a specific packaging variant of the general 74LS174 function code. It serves as a foundational building block for sequential logic design in legacy and industrial control applications.

Flip Flops Replacement Considerations

Equivalent parts include the SN54LS174J, MM74LS174N, and MC74LS174P from other manufacturers. Verify pin compatibility and electrical characteristics before substitution. The SN74LS174N is a direct functional equivalent in a different package style.
