TC7MPB9307FT(EL)

Overview

The TC7MPB9307FT(EL) is a CMOS 8-bit dual-supply bus switch designed for bidirectional level shifting between nodes operating at different voltage levels. It supports VCCA ranges of 1.65V to 5.0V and VCCB ranges of 2.3V to 5.5V, enabling interfaces such as 1.8V to 5.0V or 3.3V to 5.0V. The device features low on-resistance (typical 5.0Ω), power-down protection, and OE input tolerance up to 5.5V. It operates within a temperature range of -40°C to 125°C and is housed in a 20-TSSOP package.

Feature Summary

• Bidirectional level-shifting capability between independent power supplies without restrictions on relative voltage magnitudes
• Single common Output Enable (OE) input controls connection or isolation for all eight data lines simultaneously
• Power-down protection with 5.5V tolerance at the OE input to prevent malfunction during power transitions
• AEC-Q100 Grade 1 qualification ensuring reliability under automotive-grade environmental conditions

Applications

• Interface connections between digital logic circuits operating at distinct voltage domains
• Bidirectional data bus switching in systems requiring voltage translation
• Level shifting applications utilizing external pull-up resistors for signal integrity

Procurement Notes

Verify the specific manufacturing date code against the April 2020 cutoff when extended temperature operation (-40°C to 125°C) is required, as this specification applies only to units produced after that date. Confirm package variant requirements, noting that ordering suffixes may dictate TSSOP20 versus TSSOP20B physical dimensions. Ensure design compliance with absolute maximum ratings regarding supply voltage and current limits to maintain device reliability.

Selection Notes

Select this component when an 8-bit wide bidirectional interface is necessary between disparate voltage rails. The device is suitable for designs requiring low on-resistance and robust power-down protection. Consider the specific VCCA and VCCB voltage combinations supported by the datasheet to ensure compatibility with system power architecture. Verify thermal derating requirements if operating above 85°C.
