The SN74S240N from Texas Instruments is an octal buffer and line driver designed for high-performance applications. This device features 8 channels, functioning as inverting buffers with 3-state outputs, suitable for driving bus lines or buffer memory address registers.
Key electrical characteristics include a supply voltage range of 4.75V to 5.25V, with a maximum propagation delay of 15 ns at 5V. It supports output currents of up to 64mA (IOL) and -15mA (IOH). The inputs are tolerant down to 2V and compatible with 3.3V or 2.5V logic, while PNP inputs reduce DC loading. Hysteresis at the inputs improves noise margins.
This component is housed in a 20-pin PDIP package and is designed for through-hole mounting. The operating temperature range is from 0°C to 70°C. The SN74S240N is part of the SNx4S24x family, known for its high fan-out and improved fan-in capabilities.
