UM3208 Datasheet (Union Semiconductor) - 8-Bit Bidirectional Voltage-Level Translator

UM3208, 8-Bit Bidirectional Voltage-Level Translator

The UM3208 is ±15kV 8-channel ESD-protected level translator provide the level shifting necessary to allow data transfer in a multi-voltage system.

Externally applied voltages, VCCB and VCCA, set the logic levels on either side of the device.
