74AC174MTR

Flip Flops Overview

The STMicroelectronics 74AC174MTR is a Hex D-type flip-flop with clear, manufactured using advanced sub-micron silicon gate C2MOS technology. It features six independent D-type flip-flops in a single package, providing positive-edge triggering and asynchronous clear functionality. The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 125 MHz at 5V. It utilizes a 16-SOIC surface-mount package with a width of 0.154 inches (3.90mm). Key electrical characteristics include low power dissipation and high-speed performance suitable for complex digital logic applications.

Flip Flops Feature Summary

• Hex configuration containing six independent D-type flip-flops with positive-edge triggering
• Asynchronous clear function allows immediate reset of all outputs regardless of clock state
• Advanced C2MOS technology ensures high-speed operation with low power consumption
• Tri-state outputs provide controlled bus driving capabilities

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in communication interfaces
• General-purpose storage elements in microprocessor systems
• Timing delay lines and pulse synchronization circuits

Flip Flops Procurement Notes

Verify the specific suffix MTR indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as it may vary by production batch or region. Check for obsolescence notices from STMicroelectronics, as older CMOS logic families are frequently phased out. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Flip Flops Selection Notes

Select this component when a hex D-type flip-flop with clear is required in a small surface-mount package. Compare propagation delays and output drive currents against alternative logic families if speed is critical. Verify that the 16-SOIC footprint matches the PCB layout constraints. Consider thermal dissipation requirements given the low power nature of CMOS technology.

Flip Flops Part Context

This part belongs to the 74AC series of advanced CMOS logic devices, known for compatibility with 74LS inputs while offering faster switching speeds. The 74AC174 specifically provides hex D-type functionality, distinguishing it from octal variants like the 74AC574 which lack the clear pin. It serves as a fundamental building block for sequential logic design in industrial and consumer electronics.

Flip Flops Replacement Considerations

Direct substitutes include the SN74AC174 from Texas Instruments and MC74AC174DWG from onsemi. These alternatives maintain pinout compatibility and logical functionality. Verify package dimensions and electrical specifications match before substitution.
