Overview
The SN54LS05J is a military-grade hex inverter from the Texas Instruments LS series, housed in a 14-pin ceramic dual in-line package (CDIP). 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 operating temperature range of -55°C to 125°C. Propagation delays are specified between 15 ns and 32 ns under standard test conditions.
Feature Summary
- Contains six independent inverting circuits
- Features open-collector output configuration requiring external pull-up resistors
- Supports active-low wired-OR or active-high wire-AND logic functions
Applications
- Military and defense electronic systems
- High-voltage output generation interfaces
- Bus driver applications requiring wired logic capabilities
Procurement Notes
Verify that the component matches the specific SN54LS05J part number and CDIP-14 package configuration. Confirm the manufacturer origin and check for any military qualification markings such as JM38510/07004BCA if required for the application. Ensure the device meets the specified -55°C to 125°C temperature rating.
Selection Notes
Select this component when high reliability and wide temperature tolerance are required for inverter logic. The open-collector design allows interfacing with different voltage levels via pull-up selection. Consider the ceramic package for superior environmental stability compared to plastic variants in harsh operating conditions.
Part Context
This device belongs to the SN54LS05 family of hex inverters with open-collector outputs. It is distinct from the commercial SN74LS05 variant by its extended temperature range and ruggedized packaging. The 'J' suffix specifically denotes the ceramic dual in-line package suitable for demanding environments.

FAQ
Why are external components necessary for the SN54LS05J?
The open-collector outputs require external pull-up resistors to function correctly and establish a high logic state.
What logic functions can be implemented using the open-collector outputs?
Connecting multiple outputs together enables active-low wired-OR or active-high wire-AND functions.
