ADG3308BCPZ-REEL7

Translators, Level Shifters Overview

The ADG3308BCPZ-REel7 is a bidirectional logic level translator featuring eight channels in a 20-lead LFCSP package. It operates with VCCA from 1.15 V to 5.5 V and VCCY from 1.65 V to 5.5 V, requiring VCCA ≤ VCCY. Quiescent current is less than 1 μA. Maximum data rates range from 25 Mbps to 60 Mbps depending on voltage combinations. Propagation delays are typically 4 ns to 18 ns. The device supports three-state operation via an EN pin and functions within the -40°C to +85°C temperature range.

Translators, Level Shifters Feature Summary

• Bidirectional translation between A-side (VCCA) and Y-side (VCCY) without direction control pins
• Low quiescent power consumption suitable for battery-operated systems
• Three-state capability controlled by the EN pin for power saving

Translators, Level Shifters Applications

• Low voltage ASIC level translation
• Smart card readers
• Cell phones and cell phone cradles
• Portable communication devices
• Telecommunications equipment

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix REEL7 corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the specific B version industrial temperature rating (-40°C to +85°C) matches system environmental requirements. Ensure supply sequencing allows VCCY to rise before or simultaneously with VCCA to prevent improper biasing during power-up.

Translators, Level Shifters Selection Notes

Select this component when interfacing digital buses operating at different voltage levels, such as 1.8 V to 3.3 V or 3.3 V to 5 V. The absence of a direction pin simplifies PCB layout compared to directional translators. Verify that the maximum data rate supported by the specific VCCA/VCCY combination meets the bus speed requirements of the connected devices.

Translators, Level Shifters Part Context

This part belongs to the ADG3308 family of low-voltage level translators manufactured by Analog Devices Inc. It is functionally similar to the ADG3308-1 but utilizes a 20-lead LFCSP package instead of WLCSP. The BC suffix indicates the extended industrial temperature grade. It serves as a bridge for multivoltage digital systems connecting controllers to peripheral devices.

Translators, Level Shifters FAQ

What is the relationship 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.

How does the enable pin affect the I/O pins?

When the EN pin is pulled low, both the A side and Y side terminals enter a high impedance state. Driving EN high enables normal level translation operation.
