4-Bit Bidirectional Voltage-Level Translator for Open-Drain and Push-Pull Application UM3204H CSP12 1.9×1.4 UM3204Q QFN14 3.5×3.5 UM3204UE TSSOP14 General Description 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. A low-voltage logic signal present on the VCCA side of the device appears as a high-voltage logic signal on the VCCB side of the device, and vice-versa. The UM3204 bidirectional level translator utilizes a transmission-gate based design to allow data translation in either...
