74V1G79STR

Overview

The STMicroelectronics 74V1G79STR is a single D-type flip-flop with reset, manufactured using advanced CMOS technology. It operates within a supply voltage range of 1.65 V to 3.6 V and features high-speed data transfer capabilities. The device includes an asynchronous reset input that forces the Q output to a low state independently of the clock signal. Designed for portable applications, it offers low power consumption and supports 5 V tolerant inputs and outputs, ensuring compatibility with mixed-voltage systems.

Feature Summary

• Single D-type flip-flop with asynchronous reset functionality
• High-speed operation suitable for portable applications
• Low power consumption with CMOS technology
• 5 V tolerant inputs and outputs for mixed-voltage interfacing

Applications

• Portable consumer electronics

• Shift registers in communication systems
• Timing control circuits

Procurement Notes

Verify the specific ordering suffix 'STR' corresponds to the required tape-and-reel packaging configuration as defined in the official datasheet. Confirm that the device meets the necessary automotive or industrial qualification standards if applicable to your design requirements. Ensure compatibility with the intended voltage levels and interface protocols before finalizing procurement.

Selection Notes

Select this component when a compact, single D-flip-flop with reset is needed for low-voltage digital logic applications. Consider its 5 V tolerance feature if interfacing between 1.8 V/2.5 V/3.3 V domains and 5 V systems. Evaluate the package size and pinout against board space constraints and ensure the asynchronous reset timing aligns with system synchronization requirements.

Part Context

This part belongs to the 74V series of logic ICs from STMicroelectronics, designed for low-voltage applications. It complements other devices in the family such as buffers, inverters, and gates, providing essential sequential logic functions. The series is characterized by high speed, low power, and robust ESD protection, making it suitable for modern portable and battery-powered electronic designs.

Replacement Considerations

Check for direct pin-to-pin replacements within the same 74V series or compatible families from other manufacturers. Verify that any substitute maintains the same voltage range, speed characteristics, and package dimensions. Ensure the replacement device also supports the required 5 V tolerance and reset functionality without altering the circuit's timing behavior.
