SN74ALVTH162244 具有三态输出的 2.5V/3.3V 16 位缓冲器/驱动器
SN74ALVTH162244 描述
The 'ALVTH162244 devices are 16-bit buffers/line drivers designed for low-voltage 2.5-V or 3.3-V VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.
These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetrical active-low output-enable (OE\) inputs.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
When VCC is between 0 and 1.2 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.2 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
