转换 - 电压电平 Low VTG 1.15V-5.5V 8-CH Bidirect Logic

Low Voltage, 1.15 V to 5.5 V, 8-Channel  Bidirectional Logic Level Translators

GENERAL DESCRIPTION ADG3308BRUZ

The ADG3308/ADG3308-1 are bidirectional level translators containing eight bidirectional channels. They can be used in multivoltage digital system applications, such as a data transfer between a low voltage DSP controller and a higher voltage device. The internal architecture allows the device to perform bidirectional level translation without an additional signal to set the direction in which the translation takes place.

The voltage applied to VCCA sets the logic levels on the A side  of the device, and VCCY sets the levels on the Y side. For proper  operation, VCCA must always be less than VCCY. The VCCA  compatible logic signals applied to the A side of the device  appear as VCCY compatible levels on the Y side. Similarly, VCCY  compatible logic levels applied to the Y side of the device appear  as VCCA compatible logic levels on the A side.
