Texas Instruments SN74LVC541APWR Octal Buffer Driver, 20-Pin TSSOP
Texas Instruments 1.65-3.6V octal buffer/driver with 3-state outputs for voltage translation in industrial, comms & computing applications.
The Texas Instruments SN74LVC541APWR is a high-performance octal buffer and line driver designed for operation at voltages from 1.65V to 3.6V. Housed in a compact TSSOP-20 package, this integrated circuit features 3-state outputs, providing a high-impedance state for efficient bus management. Its design facilitates straightforward printed circuit board (PCB) layout, making it an excellent choice for complex electronic systems.
A key feature is the 3-state control gate, configured as a 2-input AND gate with active-low inputs. This ensures that if either output enable (OE1 or OE2) input is high, all eight outputs enter the high-impedance state. The device supports mixed-mode signal operation, allowing its inputs to be safely driven from either 3.3V or 5V devices. This capability makes it an ideal voltage level translator in mixed-voltage system environments, such as those found in modern industrial and communication equipment.
The device is fully specified for partial-power-down applications using its IOFF circuitry. This feature disables the outputs when the device is powered down, preventing damaging current backflow. To maintain a high-impedance state during power-up or power-down sequences, the OE pin should be tied to VCC via a pull-up resistor. The device also boasts robust latch-up performance, exceeding 250 mA per JESD 17 standards, and its inputs can accept voltages up to 5.5V, enhancing its durability and compatibility.
With a fast propagation delay of 5.1 ns at 3.3V, it ensures rapid signal transmission. It meets strict specifications for output ground bounce (VOLP) and VOH undershoot (VOHV), guaranteeing signal integrity. Furthermore, it is a green product, manufactured without antimony or bromine (Sb/Br).
