Additional Details:
The HD74ACT240FPEL-E is typically packaged in a SOP (Small Outline Package). Its operating temperature range is usually between -40°C to +85°C. The device features three-state outputs, allowing it to be effectively disconnected from the bus. For specific electrical characteristics (e.g., propagation delay, supply current), refer to the Renesas datasheet. The enable input (OE) controls all eight buffers; when OE is high, all outputs are disabled.
