BUFFER/DRIV, OCTAL, TRI-STATE, WSOIC-20; Logic Family / Base Number: 74AC540; Logic Device Type: Buffer / Line Driver, Inverting; Logic Case Style: WSOIC; No. of Pins: 20Pins; Supply Voltage Min: 2V; Supply Voltage Max: 6V; Lo
The AC540 is an octal buffer/line drivers designed to be employed as memory and address drivers, clock drivers and bus oriented transmitter/receivers. These devices are similar in function to the AC240 while providing flow-through architecture (inputs on opposite side from outputs). This pinout arrangement makes these devices especially useful as output ports for microprocessors, allowing ease of layout and greater PC board density.
