ADG3304BRUZ Low Voltage, 1.15 V to 5.5 V, 4-Channel, Bidirectional Logic Level Translator

RS Components Part # 412-826

Manufactured by Analog Devices - Part # ADG3304BRUZ - TSSOP14 SMD Package

DESCRIPTION

The ADG3304 is a bidirectional logic level translator that contains four bidirectional channels. It can be used in multivoltage digital system applications, such as data transfer, between a low voltage digital signal processing controller and a higher voltage device using SPI^® and MICROWIRE™ interfaces. The internal architecture allows the device to perform bidirectional logic level translation without an additional signal to set the direction in which the translation takes place.

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