74F827SPC

Overview

The onsemi 74F827SPC is a 10-bit bus buffer and line driver housed in a 24-lead Plastic Dual-In-Line (PDIP) package. It operates within a supply voltage range of +4.5V to +5.5V. The device features three-state outputs capable of sinking 64 mA and sourcing 15 mA, with propagation delays ranging from 1.0 ns to 7.5 ns depending on load conditions. It includes input clamp diodes for high-speed termination control.

Feature Summary

• Provides 3-state output buffering controlled by dedicated Output Enable pins
• Designed as a non-inverting line driver for memory address and clock applications
• Incorporates input clamp diodes to limit high-speed termination effects

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitters and receivers

Procurement Notes

Verify the specific ordering code suffix against current manufacturer documentation to confirm package type and availability status. Ensure compatibility with existing system voltage requirements and interface standards before procurement. Confirm that the component meets necessary environmental and safety certifications for the intended deployment environment.

Selection Notes

Select this component when a non-inverting 10-bit buffer is required for wide data paths or parity buses. Compare performance metrics such as propagation delay and output drive strength against alternative logic families. Consider the PDIP package constraints regarding board density and thermal management relative to surface-mount alternatives.

Part Context

This part belongs to the 74F series of high-speed logic devices. It functions as the non-inverting counterpart to the 74F828. Both devices share identical pinouts and electrical characteristics except for signal inversion. They are designed to improve printed circuit board density in systems requiring extensive bus interfacing.

Replacement Considerations

The 74F828SPC serves as the direct functional substitute, differing only in its inverting output configuration. Verify that the system design accommodates the logical inversion if swapping between these two variants.
