74F827SPC

Overview

The Fairchild Semiconductor 74F827SPC is a 10-bit buffer and line driver belonging to the F/FAST logic series. It features true, non-inverting outputs with a 3-state capability controlled by an active-low enable signal. The device is housed in a 24-pin PDIP package with a 0.300-inch (7.62mm) width. Designed for TTL compatibility, it supports through-hole mounting and operates within a standard temperature range up to 70°C. The component handles a maximum output current of 64mA and drives a load capacitance of 50pF.

Feature Summary

• Provides 10-bit non-inverting buffering with true output polarity
• Features 3-state outputs for bus-oriented applications
• Includes dual output enable control with active-low logic
• Compatible with TTL input levels

Applications

• Bus-oriented memory systems
• Clock drivers
• Buffering applications requiring high fan-out

Procurement Notes

Verify the specific manufacturer origin, as this part was produced by both Fairchild Semiconductor and National Semiconductor prior to their merger. Confirm the package type matches the required 24-pin DIP specification. Check for RoHS compliance status if environmental regulations apply to the assembly. Ensure the product status is reviewed, as this component may be listed as obsolete depending on the current distributor inventory.

Selection Notes

Select this component when a 10-bit non-inverting buffer with 3-state control is required for TTL-based designs. The F/FAST series offers faster switching speeds compared to standard 74LS equivalents. Consider the PDIP package constraints for PCB layout and thermal management. Verify that the 64mA drive current meets the load requirements of the connected circuitry.

Part Context

This device is part of the 74F family of high-speed CMOS logic components. It serves as a digital buffer, isolating stages or driving multiple loads. The 74F827 is functionally similar to other 10-bit drivers but distinguished by its specific pinout and 3-state enable configuration. It is often used in conjunction with receivers like the 74F828 for bidirectional data transmission.

Replacement Considerations

The 74F828SC is a related component offering non-inverting 3-state functionality, though it may differ in output polarity or package details. Cross-reference with National Semiconductor equivalents if sourcing from legacy inventories. Verify pin compatibility before substituting with other 10-bit bus drivers.
