74VHC174FT

Overview

The Toshiba Semiconductor and Storage 74VHC174FT is a high-speed CMOS logic integrated circuit belonging to the 74VHC series. It functions as a hex D-type flip-flop with an asynchronous clear input, providing positive-edge triggered data storage for six independent channels within a single package. The device utilizes push-pull outputs to drive loads effectively across various digital systems. It operates reliably within a supply voltage range of 2 V to 5.5 V, ensuring compatibility with both 3.3 V and 5 V logic families. The component is housed in a compact 16-TSSOP surface-mount package, suitable for space-constrained designs. It supports a wide operating temperature range from -40°C to +125°C, making it robust for industrial applications.

Feature Summary

• Hex D-type flip-flop architecture with asynchronous clear functionality
• High-speed CMOS technology optimized for low power consumption
• Push-pull output configuration for strong signal driving capability

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data buffering
• General-purpose memory elements in digital control systems

Procurement Notes

Verify the specific manufacturer part number against official Toshiba Semiconductor and Storage documentation to ensure authenticity. Confirm that the ordering suffix matches the required packaging format, such as tape and reel or cut tape, as these variations affect physical handling but not electrical performance. Cross-reference the RoHS compliance status and lead times directly with authorized distributors to align with project timelines and regulatory requirements.

Selection Notes

Select this component when a design requires multiple independent D-type flip-flops with a common clear function in a small footprint. The 74VHC series offers superior speed compared to standard 74HC devices while maintaining lower power dissipation. Ensure the system's operating voltage falls within the 2 V to 5.5 V range and that the thermal environment stays within the specified -40°C to +125°C limits for reliable operation.

Part Context

The 74VHC174FT is part of Toshiba's extensive portfolio of high-performance logic ICs designed for modern embedded systems. As a member of the 74VHC family, it bridges the gap between traditional 5 V logic and lower voltage 3.3 V standards. This specific model provides a cost-effective solution for managing complex state machines and data paths without requiring multiple discrete components, thereby simplifying PCB layout and reducing overall system complexity.

Replacement Considerations

Compatible substitutes include the SN74VHC174DR from Texas Instruments and the MC74VHC174DTR2G from ON Semiconductor. These alternatives offer similar pinouts and electrical characteristics, facilitating direct replacement in existing designs. Verify that the substitute's propagation delay and output drive current meet the original application's timing and load requirements before implementation.
