Key Features

  • Latching transceiver.
  • High drive Open Collector output current with minimum output swing range of 20 to 50 ohms and is terminated on each end with a 30 to 40 ohm resistor. The 74F777 is a triple bidirectional transceiver with Open Collector B and 3.
  • State A port output drivers. A latch function is provided for the A port signals. The B port output driver is designed to sink 100mA from 2 volts to minimize crosstalk and ringing on the bus. A separate output threshold cl.
