74F174SJ

Flip Flops Overview

The onsemi 74F174SJ is a high-speed CMOS hex D flip-flop belonging to the F/FAST logic series. It features six positive-edge-triggered D-type flip-flops with true outputs, housed in a 16-pin ceramic dual in-line package (CDIP). The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 125 MHz. Designed for industrial temperature ranges from 0°C to 70°C, it provides robust signal integrity for digital data storage applications requiring fast switching speeds.

Flip Flops Feature Summary

• Contains six independent positive-edge-triggered D-type flip-flops
• Delivers true output signals without inversion
• Supports high-speed operation up to 125 MHz clock frequency
• Utilizes durable ceramic dual in-line packaging for reliable performance

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in digital systems
• High-speed memory buffer stages
• Timing control and synchronization logic blocks

Flip Flops Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm package integrity as ceramic DIP units may have specific handling requirements. Cross-reference datasheet specifications against current design needs, as legacy components may require careful integration planning. Ensure compliance with environmental regulations relevant to the deployment region.

Flip Flops Selection Notes

Select this component when six synchronized storage elements are required in a single package. Consider the ceramic package for harsh environments where plastic alternatives might fail. Evaluate the 125 MHz speed capability against system timing constraints. Verify that the 4.5V to 5.5V operating range aligns with the target power supply architecture.

Flip Flops Part Context

This part belongs to the Fairchild Semiconductor 74F series, now managed by onsemi following corporate acquisition. The 74F174 variant represents a standard hex D flip-flop configuration within the FAST logic family, known for superior speed compared to standard TTL counterparts. The SJ suffix typically denotes specific packaging or testing variations within the manufacturer's catalog structure.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include SN74F174NSR from Texas Instruments. Verify pin compatibility and electrical characteristics before substitution. Check availability as original stock is discontinued.
