100323PC

Overview

The Fairchild Semiconductor 100323PC is a low-power hex bus driver integrated circuit. It features a non-inverting configuration with true outputs, designed for TTL logic compatibility. The device is housed in a 24-pin Plastic Dual In-Line Package (PDIP). Key electrical parameters include an operating voltage range of -4.2V to -5.7V and a maximum output current capability suitable for standard digital applications. It belongs to the F/FAST series, offering high-speed performance with low power consumption.

Feature Summary

• Hex bus driver architecture providing six independent buffering channels
• Non-inverting signal path with true output polarity
• Low-power design optimized for energy efficiency
• TTL-compatible input and output levels

Applications

• High-speed data bus buffering in digital systems
• Signal isolation between different logic families
• Memory interface driving applications
• General-purpose digital logic buffering

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor has undergone corporate restructuring and acquisitions. Confirm the specific package variant matches the required 24-pin DIP form factor. Check for RoHS compliance status if environmental regulations apply to your assembly process. Ensure the part number suffix corresponds to the exact speed grade and packaging style specified in your design documentation.

Selection Notes

Select this component when a hex buffer with non-inverting functionality is required for TTL-level signals. Consider the -4.2V to -5.7V supply range constraints during power budgeting. Evaluate the PDIP-24 package dimensions against your PCB footprint requirements. Compare propagation delay specifications against system timing budgets to ensure adequate signal integrity at target frequencies.

Part Context

This component belongs to the Fairchild 100K or F/FAST logic families, which are known for high-speed operation. Hex bus drivers like the 100323PC are fundamental building blocks in digital electronics, used to drive multiple loads from a single source while maintaining signal fidelity. The 24-pin DIP package facilitates through-hole mounting for prototyping and legacy board designs.

Replacement Considerations

Direct substitutes may include other hex bus drivers from the same logic family or compatible parts from manufacturers like ON Semiconductor, which acquired Fairchild's semiconductor business. Verify pinout compatibility and electrical characteristics before substitution. Generic equivalents must match the 24-pin DIP package and non-inverting hex buffer topology.
