74ALVC164245DGGTE4

16位3.3 V至具有三态输出的5V电平转换收发器 16-BIT 3.3-V TO 5-V LEVEL SHIFTING TRANSCEIVER WITH 3-STATE OUTPUTS

DESCRIPON/ORDERING INFORMATION

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 circuitry 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.
