SNJ54LS05W

Inverter Gates Overview

The SNJ54LS05W is a military-grade hex inverter from the Texas Instruments 54LS series, housed in a 14-pin ceramic flat package (CFP). It features six independent inverters with open-collector outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended operating temperature range from -55°C to 125°C. Electrical characteristics include a low-level output current capability of up to 8 mA at VCC = 4.5 V.

Inverter Gates Feature Summary

• Contains six independent inverters with open-collector outputs requiring external pull-up resistors
• Supports active-low wired-OR or active-high wire-AND logic functions when connected to other open-collector outputs
• Designed for high VOH level generation applications
• Military-grade construction utilizing a glass-sealed ceramic flat package

Inverter Gates Applications

• Military and defense circuitry requiring wide temperature tolerance
• High-voltage interface logic conversion
• Bus driver implementations using wired-logic configurations

Inverter Gates Procurement Notes

Verify that the specific orderable part number matches the required military qualification standards and package type. Confirm RoHS exemption status as indicated in official documentation. Ensure compatibility with existing thermal management solutions due to the ceramic flat package specifications.

Inverter Gates Selection Notes

Select this component for designs necessitating military-grade reliability and operation across extreme temperatures. The open-collector architecture requires careful consideration of external pull-up resistor values to meet specific voltage and current requirements. Verify that the 14-pin CFP footprint aligns with the target PCB layout constraints.
