UM3304 4-Bit Bidirectional Voltage-Level Translator with Auto Direction Sensing and ±4kV ESD Protection UM3304 CSP12 1.9×1.4 UM3304Q QFN14 3.5×3.5 UM3304QS QFN14 3.5×3.5 UM3304QT QFN16 2.6×1.8 UM3304QA QFN12 1.7×2.0 General Description 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 to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes. Both I/O ports are auto-sensing; thus, no direction pin is required, making it ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems. The UM3304/UM3304Q/UM3304QS/UM3304QT/UM3304QA operates at a ...
