请教大家SN74AVCBH164245的问题，到底能不能做3.3-》5的电平转换

今天看了下SN74AVCBH164245的DS 似乎不支持3.3<->5的电平转换啊。但是TI的选型介绍上又说支持。。不知道哪位用过，能否告知下谢谢。。

下面把两个地方的介绍贴上来给大家看看。

DATASHEET里面的介绍：

This 16-bit (dual-octal) noninverting bus transceiver uses two separate configurable power-supply rails. The A-port is designed to track VCCA. VCCA accepts any supply voltage from 1.4 V to 3.6 V. The B-port is designed to track VCCB. VCCB accepts any supply voltage from 1.4 V to 3.6 V. This allows for universal low-voltage bidirectional translation between any of the 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

The SN74AVCBH164245 is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the outputs so the buses are effectively isolated.

但是TI网站上的介绍又是说

的确是不支持，还是以data sheet中内容为准。显然这里应该填入RECOMMENDED OPERATING CONDITIONS的值

网页上的5V只是Vcc的最大极值（-0.5 to 4.6V），请严格按照推荐工作条件来应用。

如果你需要3.3 to 5V转换，请用SN74LVC16T245.
