SN74ALVC164245 具有三态输出的 16 位 2.5V 至 3.3V/3.3V 至 5V 电平转换收发器
This 16-bit (dual-octal) noninverting bus transceiver contains two separate supply rails. B port has VCCB, which is set to operate at 3.3 V and 5 V. A port has VCCA, which is set to operate at 2.5 V and 3.3 V. This allows for translation from a 2.5-V to a 3.3-V environment, and vice versa, or from a 3.3-V to a 5-V environment, and vice versa.
The SN74ALVC164245 is designed for asynchronous communication between data buses. The control cirucitry (1DIR, 2DIR, 1OE\, and 2OE\) is powered by VCCA.
To ensure the high-impedance state during power up or power down, the output-enable (OE)\ input 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
