PI74AVC164245A数据手册集成电路（IC）的转换器电平移位器规格书PDF

描述 Description

The  PI74AVC164245A, a 16-bit (dual-octal) non inverting bus transceiver, contains two separate supply rails:B port (VCCB), set at 3.3V, and A port (VCCA), set to operate at 1.2-2.5V. This arrangement permits translation from a 1.2-2.5Vto 3.3V environment and vice versa. The PI74AVC164245A is designed for asynchronous communication between data buses. To ensure the high impedance state during power up or power down, the output-enable (OE) input should be tied to VCCB througha pullup resistor: the minimum value of the resistor is determined by the current-sinking capability of the driver.
