FEATURES

  • High impedance NPN base inputs for reduced loading (20µA in High and Low states)
  • Low power, light bus loading
  • Functionally similar to the 74F240 and 74F241
  • Provides ideal interface and increases fan-out of MOS microprocessors
  • Efficient pinout to facilitate PC board layout
  • Octal bus interface
  • 3-State buffer outputs sink 64mA
  • 15mA source current

DESCRIPTION

The 74F540 and 74F541 are octal buffers that are ideal for driving bus lines or buffer memory address registers. The outputs are capable of sinking 64mA and sourcing up to 15mA, producing very good capacitive drive characteristics. The devices feature input and outputs on opposite sides of the package to facilitate printed circuit board layout.

For conditions shown as MIN or MAX, use the appropriate value under the recommended operating conditions for the applicable type. 2. All typical values are at VCC = 5V, Tamb = 25°C. 3. Not more than one output should be shorted at a time. For testing IOS , the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, IOS should be performed last.
