The SN74HC540NSR from Texas Instruments is an octal buffer and line driver designed for high-speed switching applications. It features 3-state outputs that can drive bus lines directly or up to 15 LSTTL loads. The device operates over a wide voltage range of 2 V to 6 V, making it versatile for different system requirements.
This buffer/line driver offers a data flow-through pinout, facilitating easier printed circuit board layout. The 3-state control gate is a 2-input NOR, where either output-enable input being high places all outputs in a high-impedance state. The outputs provide inverted data. The SN74HC540NSR is housed in a 20-SOIC package and operates within a temperature range of -40°C to 85°C.
Key electrical characteristics include a low power consumption of 80-μA maximum ICC and a typical propagation delay of 8 ns. It also provides ±6-mA output drive at 5 V and a low input current of 1 μA maximum. These specifications make it suitable for applications requiring efficient buffering and signal driving.
