产品概述
The SN74LVT244BDW is an octal Buffer/Line Driver designed specifically for low-voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5V system environment. It is organized as two 4-bit line drivers with separate output-enable (OE)\ inputs. When OE\ is low, the device passes data from the A inputs to the Y outputs. When OE\ is high, the outputs are in the high-impedance state. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver. It 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.
- Supports mixed-mode signal operation
- IOFF and power-up 3-state support hot insertion
- Supports unregulated battery operation down to 2.7V
- Latch-up performance exceeds 100mA per JESD 78, class II
- <lt/>0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)
- Green product and no Sb/Br
