SN54LS04J

The SN54LS04J is a hex inverter IC from Texas Instruments, part of the 54LS series (military-grade, wide temperature range). It contains six independent NOT gates, each with a Schottky-clamped transistor for fast switching.
Key Features:
- Logic Type: Inverter (NOT gate)
- Supply Voltage: 4.5V to 5.5V (TTL compatible)
- Propagation Delay: ~9.5ns (typical)
- Operating Temp: -55°C to +125°C (military spec)
- Package: Ceramic DIP (J-suffix)
Applications:
- Signal inversion in digital circuits
- Pulse shaping, buffering, and logic level correction
Differences from SN74LS04:
- 54LS is ruggedized for harsh environments vs. 74LS (commercial grade).
A reliable choice for high-reliability systems like aerospace or industrial controls.
