JD54F244SRA

Overview

The JD54F244SRA is an octal buffer and line driver manufactured by National Semiconductor. It features two non-inverting buffers, each with four bits and three-state outputs. The device is housed in a 20-pin CERDIP package. It operates within a supply voltage range of 4.75V to 5.25V. The component is designed for high-speed digital applications requiring signal buffering and line driving capabilities.

Feature Summary

• Provides octal buffering with independent control of two four-bit sections
• Features three-state outputs to facilitate bus-oriented systems
• Non-inverting logic function preserves input signal polarity

Applications

• Bus-oriented systems requiring signal isolation
• Memory address drivers
• Clock drivers and buffering

Procurement Notes

Verify the manufacturer date code and lot traceability when sourcing this component. Ensure the packaging matches the specified 20-CERDIP form factor. Confirm that the device meets the required military or industrial temperature specifications if applicable to your design constraints.

Selection Notes

Select this part when an octal buffer with three-state capability is required. Consider the 20-pin CERDIP package for through-hole mounting needs. Evaluate the propagation delay and drive current requirements against the load conditions of the target circuit to ensure signal integrity.

Part Context

This component belongs to the 54F series of logic devices, known for faster switching speeds compared to standard TTL. The 54F244 variant specifically provides octal buffering. The JD prefix indicates specific manufacturing or qualification details from National Semiconductor.

Replacement Considerations

Check for direct equivalents such as the SN54F244 or MC10E244 depending on package availability. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement supports the same three-state output functionality.
