产品概述
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.
