Overview
The SN74LV541APWT, produced by Texas Instruments, is an octal buffer/driver device designed for operation over a wide voltage range of 2 V to 5.5 V. This device is ideal for driving bus lines or buffering memory address registers. It features inputs and outputs on opposite sides of the package, facilitating easier printed circuit board layout. The SN74LV541A includes 3-state control gates with active-low inputs, allowing the outputs to be in a high-impedance state when either output-enable input is high. This device is fully specified for partial-power-down applications and includes Ioff circuitry to prevent damaging current backflow when powered down.
