8-bit buffer for mixed-voltage buses
The Nexperia 74ALVC541D,112 is an 8-bit non-inverting buffer with 3-state outputs from the 74ALVC family, designed for bus-oriented applications where signal drive and isolation are needed across a 1.65V to 3.6V supply range. Each output can sink or source 24mA, giving it enough fan-out to drive a moderate backplane or multiple CMOS inputs without external line drivers. The 3-state outputs let multiple buffers share a common bus line — pull the output-enable pin high and the outputs go high-impedance, which is the standard way to implement bidirectional data paths or multiplexed address/data buses.
Supply flexibility and signal-level translation
The 1.65V to 3.6V supply range means this buffer can run on a 1.8V, 2.5V, or 3.3V rail without a separate level translator — useful when bridging a low-voltage core logic domain to a 3.3V peripheral bus. Because the ALVC family is specified for high-speed operation at the lower end of the supply, the 74ALVC541D,112 maintains propagation delays in the few-nanosecond region even at 1.65V, which matters for timing closure on a fast memory or register interface.
