UM3304 Datasheet (Union Semiconductor) - 4-Bit Bidirectional Voltage-Level Translator

UM3304, 4-Bit Bidirectional Voltage-Level Translator

UM3304/UM3304Q/UM3304QS/UM3304QT/UM3304QA is quad channel level translator with auto direction sensing and ±4kV ESD protection.

This 4-channel non-inverting translator uses two separate configurable power-supply rails.

The A port is designed to track VCCA.

VCCA accepts any supply voltage from 1.2V
