74F64PC

Overview

The National Semiconductor 74F64PC is a commercial-grade logic gate belonging to the F/FAST series. It implements a 4-2-3-2-input AND-OR-invert function within a single integrated circuit. The device is housed in a 14-lead plastic dual-in-line package (PDIP) with a standard 0.300-inch width. Designed for TTL-compatible applications, it provides high-speed switching capabilities characteristic of the F-series technology.

Feature Summary

• Implements complex 4-2-3-2-input AND-OR-invert logic functionality
• High-speed switching performance typical of the F/FAST series
• TTL-compatible input and output characteristics

Applications

• Complex combinational logic circuits
• Data processing systems requiring specific AND-OR inversion
• Industrial control logic interfaces

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor's logic assets were acquired by Texas Instruments. Ensure the part number suffix matches the required package style and temperature rating. Confirm availability through authorized distributors or surplus suppliers, as original National Semiconductor production may be discontinued.

Selection Notes

Select this component when a dedicated 4-2-3-2-input AND-OR-invert gate is required without using multiple discrete gates. Consider the PDIP package constraints for board layout. Verify that the F/FAST speed class meets the system timing requirements compared to slower LS or HC series alternatives.

Part Context

This component is part of the extensive 74F logic family, known for superior speed over standard 74LS devices. The 74F64 specifically addresses designs needing complex gating structures in a compact form factor. It serves as a building block for advanced digital logic implementations where propagation delay is critical.

Replacement Considerations

Direct replacements include the SN74F64PC from Texas Instruments, which maintains functional equivalence. Other compatible variants may exist under different manufacturer designations within the same logic family specifications.
