SNJ54AHCT14J

Inverter Gates Overview

The SNJ54AHCT14J is a military-grade Hex Schmitt-Trigger Inverter manufactured by Texas Instruments. It contains six independent inverters performing the Boolean function Y = A. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from -55°C to 125°C. It features TTL-voltage compatible inputs, high ESD protection exceeding 2000-V Human-Body Model, and latch-up performance exceeding 250 mA per JESD 17.

Inverter Gates Feature Summary

• TTL-voltage compatible inputs
• High ESD protection performance
• Robust latch-up resistance

Inverter Gates Applications

• Servers
• Network switches
• Telecom infrastructures
• Tests and measurements

Inverter Gates Procurement Notes

Verify that the specific part number SNJ54AHCT14J corresponds to the Military rating and CDIP package as documented in the datasheet. Confirm compliance with MIL-PRF-38535 requirements if full parameter testing is necessary for your application. Ensure all unused inputs are properly biased to prevent undefined operational states during operation.

Inverter Gates Selection Notes

Select this component when military-grade reliability and extended temperature operation are required. The AHCT series ensures compatibility with standard TTL logic levels while providing CMOS drive capabilities. Verify that the 14-pin CDIP package fits the mechanical constraints of the target design.

Inverter Gates Part Context

This device belongs to the SNx4AHCT14 family of Hex Schmitt-Trigger Inverters. The 'SNJ' prefix indicates a military-rated version housed in a ceramic dual in-line package (CDIP). It shares functional characteristics with commercial variants but meets stricter environmental and reliability standards suitable for defense and aerospace applications.

Inverter Gates Replacement Considerations

Compatible substitutes include other SN54AHCT14 variants such as SNJ54AHCT14W or SNJ54AHCT14FK, provided the package type matches the board layout. Commercial equivalents like SN74AHCT14 may be considered only if military temperature ratings are not required.
