SN74LVT240ADBR概述

3.3 -V ABT八路缓冲器/驱动器,具有三态输出 3.3-V ABT OCTAL BUFFER/DRIVER WITH 3-STATE OUTPUTS

This octal buffer and line driver is designed specifically for low-voltage 3.3-V VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

The SN74LVT240A is organized as two 4-bit buffer/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.

When VCC is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5 V, 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.
