Texas Instruments SN74LVTH541 3.3-V ABT Octal Buffers/Drivers With 3-State Outputs SN74LVTH541DWR

The SN74LVTH541 3.3-V ABT Octal Buffers/Drivers with 3-State Outputs from Texas Instruments are designed for low-voltage operation while providing compatibility with 5-V systems. This device supports mixed-mode signal operation, allowing 5-V input and output voltages with a 3.3-V VCC. It features a typical output ground bounce (VOLP) of less than 0.8 V at 3.3 V and is capable of operating with supply voltages down to 2.7 V, making it suitable for unregulated battery applications. The SN74LVTH541 includes bus hold circuitry on data inputs, which eliminates the need for external pull-up or pull-down resistors. It is fully specified for hot-insertion applications, with Ioff and power-up 3-state support to prevent damaging current backflow during power transitions. The device also boasts robust latch-up performance exceeding 500 mA and ESD protection that exceeds JESD 22 standards, ensuring reliability in various environments. This octal buffer/driver is ideal for driving bus lines or buffering memory address registers, with inputs and outputs located on opposite sides of the package to facilitate PCB layout. The 3-state control gate is implemented as a 2-input AND gate with active-low inputs, ensuring that all outputs enter a high-impedance state when either output-enable input is high.
