SN74LS541

SN74LS541 Octal Buffer/Line Driver with 3−State Outputs The SN74LS541 is an octal buffer and line driver with the same functions as the LS241, but with pinouts on the opposite side of the package. This device type is designed to be used as a memory address driver, clock driver and bus-oriented transmitter / receiver. This device is especially useful as output ports for the microprocessors, allowing ease of layout and greater PC board density.
