74AC174SJX

Flip Flops Overview

The Fairchild Semiconductor 74AC174SJX is a high-speed hex D-type flip-flop belonging to the AC series. It features six positive edge-triggered storage registers with true outputs, designed for efficient data retention in digital logic circuits. The component utilizes CMOS technology and is housed in a 16-lead Small Outline Package (SOP). Key electrical specifications include a maximum operating frequency of 70 MHz at nominal supply voltage and a maximum output current of 12 mA. The device supports an operating temperature range from -40 °C to +85 °C and has a load capacitance rating of 50 pF.

Flip Flops Feature Summary

• Contains six independent D-type flip-flops for parallel data storage
• Positive edge-triggered clocking mechanism for precise timing control
• CMOS construction ensures reduced power consumption compared to legacy technologies
• Master reset function allows simultaneous clearing of all internal registers

Flip Flops Applications

• High-speed data storage registers in digital systems
• Parallel-to-serial conversion circuits
• State machine implementations requiring multiple storage elements
• Buffering applications for signal integrity maintenance

Flip Flops Procurement Notes

Verify that the specific suffix 'SJX' corresponds to the tape-and-reel packaging variant rather than standard tube packaging. Confirm RoHS compliance status as historical AC series parts may vary by production batch. Ensure the supplier provides documentation confirming the ceramic or plastic package material if environmental sealing is required for the application environment.

Flip Flops Selection Notes

Select this component when a hex configuration is required to minimize board space compared to using multiple dual flip-flops. The AC series offers a balance between speed and power dissipation suitable for general-purpose logic. Consider the 70 MHz frequency limit against system clock requirements. Verify input compatibility with the driving logic family to ensure proper voltage thresholds are met during operation.

Flip Flops Part Context

This part belongs to the widely adopted 74AC logic family, known for high-speed performance comparable to older TTL families but with lower power draw. The 74AC174 specifically addresses designs needing six bits of synchronous storage. It serves as a direct functional replacement for other hex D-flip-flops in the 74HCT or 74HC series, though pinout and voltage levels must be checked for compatibility.

Flip Flops Replacement Considerations

The 74AC174SC is a compatible alternative within the same manufacturer's lineup offering identical logical functionality. Cross-manufacturer equivalents such as the SN74AC174 from Texas Instruments provide pin-compatible substitution options. Ensure that any substitute maintains the same 16-pin SOP footprint and voltage operating range.
