SN74HC540N Description

Short technical summary and product information.

The SN74HC540N from Texas Instruments is an octal buffer and line driver designed for digital logic applications. It features 3-state, inverting outputs, allowing for direct driving of bus lines or up to 15 LSTTL loads.

 

This device operates within a wide voltage range of 2V to 6V and is specified for an operating 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. The output drive current is ±6mA at 5V.

 

The SN74HC540N is housed in a 20-pin PDIP package, designed for through-hole mounting. Its data flow-through pinout, with inputs on the opposite side from outputs, facilitates 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 the high-impedance state.
