UM3204 Datasheet (Union Semiconductor) - 4-Bit Bidirectional Voltage-Level Translator

UM3204, 4-Bit Bidirectional Voltage-Level Translator

The UM3204 is quad 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.
