SN74HC540NS Description

Short technical summary and product information.

The SN74HC540NS is an octal buffer and line driver featuring 3-state outputs, designed by Texas Instruments. This component offers a wide operating voltage range from 2V to 6V, making it versatile for different system requirements.

 

Key electrical characteristics include a typical propagation delay of 8 ns and low power consumption with a maximum ICC of 80 μA. The outputs can drive up to 15 LSTTL loads and provide ±6 mA output drive at 5V. The device features a data flow-through pinout, which simplifies PCB layout.

 

Packaged in a 20-SOIC format, the SN74HC540NS is designed for surface mounting. It operates within a temperature range of -40°C to 85°C (TA). The 3-state control gate is a 2-input NOR, allowing all outputs to be in a high-impedance state when either output-enable input is high. The outputs provide inverted data.

 

This buffer is suitable for applications requiring signal buffering, line driving, or data transmission in digital systems where inverting logic and high-impedance output states are necessary.
