ADG3304SRU-EP-RL7

Translators, Level Shifters Overview

The ADG3304SRU-EP-RL7 is a low voltage, 1.15 V to 5.5 V, 4-channel bidirectional logic level translator from Analog Devices Inc., designed for enhanced product applications. It operates within a military temperature range of −55°C to +125°C and supports defense and aerospace standards (AQEC). The device features four bidirectional channels with no direction pin requirement, utilizing an internal architecture that automatically determines translation direction. It includes an enable pin for three-state operation on both A and Y sides. The component is housed in a compact 14-lead TSSOP package.

• Bidirectional level translation without additional direction control signals
• Military temperature range operation from −55°C to +125°C
• Three-state capability via active high enable pin
• Controlled manufacturing baseline with single assembly and test site

Translators, Level Shifters Applications

• SPI and MICROWIRE level translation
• Low voltage ASIC level translation
• Smart card readers
• Portable communications devices
• Telecommunications equipment

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix SRU-EP-RL7 against the manufacturer's current documentation to confirm package type and RoHS compliance status. Ensure the procurement channel is authorized for Enhanced Product (EP) components, as these often require controlled distribution channels due to their qualification for defense and aerospace applications. Confirm availability of qualification data if required for your specific project standards.

Translators, Level Shifters Selection Notes

Select this component when operating between voltage domains ranging from 1.15 V to 5.5 V with bidirectional data flow requirements. It is suitable for systems requiring automatic direction detection without external control pins. Consider the 14-lead TSSOP package for space-constrained designs. Verify that the application environment falls within the specified −55°C to +125°C temperature range and meets AQEC standard requirements.

Translators, Level Shifters Part Context

This part belongs to the ADG3304-EP series, which is an Enhanced Product variant of the standard ADG3304. The EP designation indicates it is qualified for defense and aerospace applications under the AQEC standard. It shares the same functional specifications as the commercial version but adheres to stricter manufacturing controls, including a single fabrication site and product change notification protocols.

Translators, Level Shifters Replacement Considerations

The ADG3304SRUZ-EP-RL7 is a RoHS-compliant alternative within the same family. Standard commercial versions like the ADG3304BRUZ lack the military temperature range and AQEC qualification. Direct substitution requires verifying that the replacement meets the specific environmental and reliability requirements of the original design.
