The 74ACT240SCX is a high-speed, inverting octal buffer from onsemi, designed for 5V digital systems. Operating from 4.5V to 5.5V, it provides 24mA of output drive current per channel, making it suitable for bus interfacing, signal inversion, and line driving. Its 3-State outputs allow for connection to shared buses, and the 20-SOIC package is ideal for space-constrained designs.
- TTL-Compatible Inputs: Directly interfaces with legacy TTL logic without additional level shifting.
- High Output Drive (24mA): Ensures reliable signal transmission to multiple loads and long traces.
- 3-State Outputs: Enables bus-oriented applications and prevents bus contention.
- Inverting Function: Provides signal inversion, reducing the need for external inverters.
