74HC540 is a 20 Pin Octal 3-state Inverting Buffer IC having 2V to 6V Operating Voltage range with 6mA output current. The 3-STATE  buffers  utilize  advanced  silicon-gate  CMOS  technology.  They  possess  high  drive  current  outputs  which enable  high  speed operation  even  when  driving  large  bus  capacitances. These  circuits  achieve  speeds  comparable  to  low  power Schottky devices, while retaining the advantage of CMOS circuitry, i.e., high noise immunity, and low power consumption. Both devices have a fanout of 15 LS-TTL equivalent inputs. The  74HC540  is  an  inverting  buffer  and  the MM74HC541 is a non-inverting buffer. The 3-STATE control gate operates as a two-input NOR such that if either G1 or  G2  are  HIGH,  all  eight  outputs  are  in  the  high-impedance state.
