74F175PC

Flip Flops Overview

The onsemi 74F175PC is a discontinued D-type flip-flop integrated circuit belonging to the 74F logic series. It contains one four-bit register with positive-edge triggering and a master reset function. The device operates within a supply voltage range of 4.5V to 5.5V, featuring a maximum propagation delay of 8.5ns at 5V with 50pF load. It utilizes a 16-SOIC surface-mount package and supports a clock frequency up to 140 MHz. Static current consumption is specified at 34 mA, with output drive capabilities of 1mA high and 20mA low.

Flip Flops Feature Summary

• Contains a single four-bit D-type flip-flop register with positive-edge clock triggering
• Includes a dedicated master reset input for synchronous data initialization
• Provides complementary outputs for each bit position

Flip Flops Applications

• High-speed digital data storage and buffering circuits
• Parallel-to-serial or serial-to-parallel data conversion modules
• State machine implementation in fast logic systems

Flip Flops Procurement Notes

This component is officially classified as obsolete and no longer manufactured by onsemi. Procurement must rely exclusively on surplus distributors or secondary market channels. Verify part authenticity and physical condition carefully, as availability varies significantly. Cross-reference with direct replacement options from other manufacturers if new production units are required for long-term designs.

Flip Flops Selection Notes

Select this component only for legacy system maintenance or specific historical design preservation where the 74F series characteristics are mandatory. Evaluate the 8.5ns propagation delay and 140 MHz clock limit against current system timing requirements. Consider that the SOIC package requires surface-mount assembly processes. Assess total cost of ownership including potential scarcity premiums when sourcing from non-OEM suppliers.

Flip Flops Part Context

The 74F175PC belongs to the 74F (Fast) logic family, known for higher speed performance compared to standard TTL variants. As a four-bit D-type flip-flop, it serves fundamental sequential logic roles in digital electronics. The device represents an older generation of semiconductor manufacturing technology, now superseded by newer process nodes offering improved power efficiency and integration density.

Flip Flops Replacement Considerations

Direct substitute part numbers include SN74F175D and SN74F175DR from Texas Instruments. These alternatives offer identical logical functionality and pinout compatibility. Verify package dimensions and electrical specifications match original design constraints before substitution.
