74F51PC

Overview

The Fairchild Semiconductor 74F51PC is a dual AND-OR-Invert (AOI) gate integrated circuit belonging to the 74F series. It features two independent logic functions: one 2-wide 2-input AOI and one 2-wide 3-input AOI. The device utilizes a 14-pin DIP package with a plastic/epoxy body. Key electrical parameters include a maximum output current of 0.02 A, an operating temperature range of 0°C to 70°C, and a synchronous binary counter configuration context within the broader F/FAST family. It contains six inputs total across its two functional blocks.

Feature Summary

• Dual configurable AND-OR-Invert logic structure supporting multiple input combinations
• Fast switching performance characteristic of the 74F series technology
• Single-ended output type for standard digital interfacing

Applications

• Digital logic circuits requiring complex AND-OR-Invert functionality
• Microprocessor system address decoding
• General-purpose combinational logic design

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm package integrity and pin alignment upon receipt. Check for RoHS compliance status as indicated in specific datasheets, noting that some legacy variants may not meet current environmental standards. Ensure storage conditions prevent moisture damage to the plastic epoxy package before soldering.

Selection Notes

Select this component when a single IC provides both 2-input and 3-input AND-OR-Invert functions. Compare against other 74F series gates for speed and power consumption requirements. Ensure the 14-pin DIP form factor fits the target PCB layout. Verify voltage levels match the system logic family specifications.

Part Context

This part belongs to the Fairchild 74F (Fast) logic family, known for high-speed operation compared to standard TTL. It serves as a multi-function gate solution, reducing component count in designs needing mixed AOI configurations. The 74F51PC specifically addresses applications requiring two distinct AOI structures within one package.

Replacement Considerations

Compatible substitutes include the 74F51SC variant which shares identical logical functionality but differs in package style. Other manufacturers producing equivalent 74F-series AOI gates may offer pin-compatible alternatives. Verify electrical characteristics and package dimensions before substitution.
