74VHC175N

Overview

The Fairchild Semiconductor 74VHC175N is a Quad D-Type Flip-Flop belonging to the 74VHC series. It features four positive-edge-triggered D-type flip-flops with complementary outputs in a 16-pin PDIP package. The device operates within a supply voltage range of 2V to 5.5V, supporting a maximum clock frequency of 115 MHz. It exhibits a typical propagation delay of 9.3ns at 5V with 50pF load and maintains a low static current of 4µA.

Feature Summary

• Provides four independent positive-edge-triggered D-type flip-flops with complementary outputs for data storage applications.
• Features high-speed CMOS technology enabling operation comparable to low-power Schottky TTL devices while maintaining low power consumption.
• Includes a master reset function to initialize all flip-flops simultaneously.

Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• Register arrays for temporary data storage in digital systems
• Timing control logic and state machine implementations

Procurement Notes

Verify that the specific part number matches the 16-PDIP through-hole package configuration required for your board layout. Confirm the manufacturer source is Fairchild Semiconductor or an authorized distributor to ensure component authenticity. Check RoHS compliance status if environmental regulations apply to your assembly process. Ensure the operating temperature range meets your system's thermal requirements.

Selection Notes

Select this component when a quad D-type flip-flop with complementary outputs is needed in a DIP package. The 74VHC series offers speed similar to LS-TTL but with lower power dissipation. Consider the 115 MHz clock limit and 2V-5.5V supply range for compatibility with your logic levels. This part is suitable for general-purpose high-speed digital buffering and storage tasks.

Part Context

The 74VHC175N is part of the 74VHC (Very High Speed CMOS) family, designed to interface between CMOS and TTL logic systems. It provides high drive current outputs capable of driving large bus capacitances. The device utilizes advanced silicon-gate CMOS technology to achieve speeds comparable to low-power Schottky devices while retaining the low power consumption advantages of standard CMOS logic families.

Replacement Considerations

Equivalent parts include the ON Semiconductor 74VHC175N and Fairchild 74VHC175MTCX in alternative packages. Cross-reference pinouts and electrical specifications to ensure functional compatibility. Verify that substitute components meet the same voltage and temperature operating ranges.
