SNJ54ALS1035J

Overview

The SNJ54ALS1035J is a military-grade hex noninverting buffer featuring open-collector outputs, housed in a 14-pin ceramic dual in-line package (CDIP). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended temperature range from -55°C to 125°C. The device provides six independent buffers with a propagation delay of 5 ns maximum at low-to-high transitions and 2 ns maximum at high-to-low transitions under standard load conditions.

Feature Summary

• Contains six independent noninverting buffers performing the Boolean function Y = A
• Features open-collector outputs requiring external pullup resistors for proper operation
• Supports active-low wired-OR or active-high wired-AND logic configurations

Applications

• Military and defense applications requiring QML certification
• Generating higher output voltage levels via external pullups
• Implementing wired-logic functions in digital circuits

Procurement Notes

Verify that the specific orderable part number matches the required package type and temperature rating. Confirm RoHS compliance status and lead finish specifications against project requirements. Ensure the component meets MIL-PRF-38535 standards if military qualification is mandated for the application.

Selection Notes

Select this component when high-drive capability with open-collector topology is required for bus sharing or voltage translation. Consider the CDIP package for hermetic sealing needs in harsh environments. Evaluate the ALS series speed-power trade-offs against alternative logic families for system optimization.

Part Context

This device belongs to the Texas Instruments 54ALS/74ALS logic family, designed for advanced low-power Schottky performance. The 'SNJ' prefix indicates a military-grade version certified to MIL-PRF-38535, ensuring reliability for aerospace and defense systems compared to commercial catalog equivalents.

Replacement Considerations

Direct replacements include other SNJ54ALS1035 variants such as the SNJ54ALS1035W (CFP) or SNJ54ALS1035FK (LCCC), provided pin compatibility and environmental ratings align with the design constraints.
