HM5302
Dual-Supply, 2-Bit Voltage Translator / Isolator for
I2C Applications
General Description
The HM5302 is a high-performance configurable dual-voltage-supply translator for bi-directional voltage translation over a wide range of input and output voltages levels. The HM5302 also works in a push-pull environment.
It is intended for use as a voltage translator between I2C-Bus compliant masters and slaves. Internal 10KΩ pull-up resistors are provided.
The device is designed so the A port tracks the VCCA level and the B port tracks the VCCB level. This allows for bi-directional A/B-port voltage translation between any two levels from 1.65V to 5.5V. VCCA can equal VCCB from1.65V to 5.5V. Either VCC can be powered-up first.
