SN74ABT245B的产品详情:

These octal bus transceivers are designed for asynchronous communication between data buses. The devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE)\ input can be used to disable the device so the buses are effectively isolated.

To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

This device is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.

SN74ABT245B的优势和特性:
  • Typical VOLP (Output Ground Bounce) <1 V at VCC = 5 V, TA = 25°C
  • Ioff and Power-Up 3-State Support Hot Insertion
  • High-Drive Outputs (–32-mA IOH, 64-mA IOL)
  • Latch-Up Performance Exceeds 500 mA Per JEDEC Standard JESD 17
  • ESD Protection Exceeds JESD 22
    • 2000-V Human-Body Model (A114-A)
    • 200-V Machine Model (A115-A)
