SN74LS540NSR Description

Short technical summary and product information.

The SN74LS540NSR is an octal buffer and line driver IC from Texas Instruments, designed with active 3-state outputs. This component features a supply voltage range of 4.75V to 5.25V and operates within a temperature range of 0°C to 70°C.

 

Key electrical characteristics include 8 channels, bipolar input type, and inverting logic. The output type is 3-state, capable of driving bus lines or buffer memory address registers. It offers an output current of 15mA and 24mA, with a maximum supply current of 52000µA. The device also includes input clamp diodes for improved performance.

 

Packaged in a 20-SOIC surface mount configuration, the SN74LS540NSR is suitable for various electronic designs requiring buffering and signal driving capabilities. Its design enhances printed circuit board layout with inputs and outputs on opposite sides of the package. The three-state control gate is a 2-input NOR, enabling high-impedance states when control signals are high.
