描述
由其分销商提供的 onsemi 74F540PC 的描述。
8 64mA 4.5V~5.5V 3mA 1 PDIP-20 Buffer/Driver/Transceiver ROHS
Bus Driver, F/FAST Series, 1-Func, 8-Bit, Inverted Output, TTL, PDIP20
Tube WITH DUAL OUTPUT ENABLE Not Qualified MATTE TIN logic driver 3mA 64mA 5.5ns 26.075mm 5V
The 74F540 and 74F541 are similar in function to the74F240 and 74F244 respectively, except that the inputs and outputs are on opposite sides of the package (seeConnection Diagrams). This pin out arrangement makes these devices especially useful as output ports for micro-processors, allowing ease of layout and greater PC board density.
