The SNJ54AC245W is a high-speed, non-inverting transceiver from the 54AC logic family. It features a single channel with 3-State outputs, capable of driving 24mA of current. Operating from 2V to 6V, it supports both 3.3V and 5V systems. Housed in a 20-pin ceramic CFlatPack, it operates from -55°C to 125°C, making it suitable for military, aerospace, and other high-reliability applications requiring high-speed data transfer.
- Wide Supply Voltage Range: 2V to 6V operation allows use in both 3.3V and 5V systems without level shifting.
- High Output Drive: 24mA sink/source capability drives heavy capacitive loads and long bus traces.
- High-Speed CMOS: Faster propagation delay compared to standard TTL, enabling higher data rates.
- Ceramic Flat Package: Low-profile, hermetic package ideal for space-constrained, high-reliability designs.
