DS55107J

Overview

The DS55107J is a high-speed Schottky TTL quad bus driver manufactured by National Semiconductor. It features four independent drivers with open-collector outputs, designed for driving buses and other high-current loads. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports data rates up to 35 MHz. It utilizes a 16-pin ceramic dual in-line package (DIP) suitable for military applications. Key electrical characteristics include a propagation delay of typically 8 ns and an output current capability of 24 mA per pin.

Procurement Notes

Verify the manufacturer date code and lot traceability when sourcing this component. Ensure that the supplier provides documentation confirming compliance with MIL-STD-883 standards if military qualification is required. Check for any specific handling instructions related to the ceramic package and lead finish.

Selection Notes

Select the DS55107J when open-collector outputs are necessary for wired-AND logic or level shifting. Consider the power dissipation limits and thermal management requirements for the DIP package. Compare propagation delays and output current specifications against system timing constraints to ensure compatibility.

Part Context

This component belongs to the SN54/74 series of high-speed Schottky TTL logic devices. It is part of a family of bus drivers designed for demanding digital applications. The 'J' suffix indicates a ceramic package, distinguishing it from plastic variants like the 'N' suffix.

Replacement Considerations

Equivalent parts include the SN54107J and SN74107J. Verify pinout compatibility and electrical specifications before substitution. Ensure that alternative components meet the same temperature range and reliability standards.
