ADG3301BKSZ-REEL

Translators, Level Shifters Overview

The ADG3301BKSZ-REEL is a single-channel bidirectional logic level translator manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.15 V to 5.5 V and features low quiescent current consumption of less than 5 µA. The device eliminates the need for direction control pins, automatically translating signals between A and Y sides based on applied voltages. It supports maximum data rates up to 60 Mbps depending on voltage configurations and is housed in a compact 6-lead SC-70 package.

Confirm that the B version temperature rating aligns with system requirements. Cross-reference pinout details with the latest datasheet revision to avoid integration errors during PCB layout.

Translators, Level Shifters Selection Notes

Select this component when interfacing digital circuits operating at different supply voltages requiring bidirectional data transfer. Ensure VCCA remains lower than or equal to VCCY during power-up sequences. Verify that the driving circuit output impedance does not exceed 150 ohms and meets peak current requirements for reliable signal integrity across the selected voltage range.

Translators, Level Shifters Part Context

This part belongs to the ADG3301 family of low-voltage level translators designed for multivoltage digital systems. It facilitates data transfer between low-voltage controllers and higher-voltage peripherals. The device simplifies design by removing timing constraints associated with separate direction signals, making it suitable for space-constrained portable and telecommunications applications.

Translators, Level Shifters FAQ

How does the ADG3301 determine the direction of translation?

The device performs automatic bidirectional translation without an additional direction signal. It detects the logic state on either the A or Y pin and translates it to the compatible voltage level on the opposite side.

What is the relationship required between VCCA and VCCY?

For proper operation, the voltage applied to VCCA must always be less than or equal to the voltage applied to VCCY. The recommended power-up sequence is VCCY first, followed by VCCA.
