GT74LVC244数据手册GTIC中文资料规格书

描述 Description

The Operating Voltage Range of the bus buffer gate is 1.65-V to 5.5-V. The GT74LVC244 devices are designed for asynchronous communication between data buses.

To ensure the high-impedance state during power up or power down, 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 partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
