SNJ54AS760J

Overview

The SNJ54AS760J is an octal buffer and line driver from the AS logic series, designed for military temperature operation ranging from -55°C to 125°C. It features open-collector outputs capable of driving bus lines or memory address registers with a low-level output current up to 64 mA at VCC = 4.5 V. The device operates on a supply voltage between 4.5 V and 5.5 V, utilizing PNP inputs to reduce DC loading. Propagation delays range from 1 ns to 19.5 ns depending on the signal path and voltage conditions.

Feature Summary

• Eliminates the need for external three-state overlap protection circuitry
• Open-collector outputs drive bus lines or buffer memory address registers
• PNP inputs reduce DC loading on preceding drivers

Applications

• 3-state memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Procurement Notes

Verify that the ordering suffix 'J' corresponds to the ceramic dual in-line package (CDIP) variant. Confirm the component meets QML certification requirements if intended for defense applications. Ensure the design accommodates the specific thermal characteristics associated with the military temperature range specified for this part number.

Selection Notes

Select this component when designing systems requiring high-density bus drivers without complex enable logic. The open-collector architecture allows wired-OR connections suitable for shared bus environments. Verify that the load capacitance and pull-up resistor values align with the required switching speeds and voltage levels for the target application.

Part Context

This device belongs to the Texas Instruments SN54AS/74AS logic family, which utilizes advanced Schottky technology for high-speed performance. The SN54 prefix indicates qualification for the full military temperature range, distinguishing it from commercial variants. It serves as an open-collector alternative to standard totem-pole buffers within the same architectural lineage.
