74F794PC

Flip Flops Overview

The Fairchild Semiconductor 74F794PC is an 8-bit D-type register featuring readback capability, housed in a 20-pin Plastic Dual-In-Line Package (PDIP). It stores data and reads register information back onto the data bus. The component operates with positive edge triggering and includes a master reset function. It is designed for high-speed applications within the 74F logic family.

Flip Flops Feature Summary

• Provides 8-bit data storage with simultaneous readback to the data bus
• Features positive edge-triggered D-type flip-flop operation
• Includes asynchronous master reset functionality
• Utilizes standard 20-lead PDIP packaging

Flip Flops Applications

• Data storage systems requiring bus readback
• High-speed sequential logic circuits
• Parallel-to-serial or serial-to-parallel data transfer interfaces
• Digital signal processing registers

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel options. Ensure compatibility with existing 74F series logic levels. Check RoHS compliance status if required by project specifications. Confirm availability as this part may be discontinued or available only as New Old Stock from third-party distributors.

Flip Flops Selection Notes

Select the 74F794PC when an 8-bit register with direct bus readback is required. It is suitable for designs needing high-speed performance characteristic of the F/FAST series. Consider the 20-pin DIP form factor for through-hole prototyping or legacy board replacements. Evaluate power consumption requirements against other 74F variants.

Flip Flops Part Context

This component belongs to the Fairchild 74F logic family, known for high speed. It is distinct from shift registers like the 74F194 or counters like the 74F191. The 74F794 serves specifically as a parallel load register with feedback capabilities, differentiating it from simple latch or flip-flop elements without readback features.

Flip Flops Replacement Considerations

Equivalent parts include the 74F794SC (SOIC package) and 74F794PCX (tape and reel). Verify pinout compatibility before substitution. Cross-reference with other manufacturers' 74F794 equivalents ensuring identical logic functions and electrical characteristics.
