Description

The SM5520 is a 2-bit bidirectional voltage translator that does not require a direction-control signal to interconnect devices operating on different voltage rails that have different I/O voltage levels. The device allows a variety of voltage translations between 1.15 V and 5.5 V in open-drain or push-pull applications. The A and B ports are designed to track VCCA and VCCB power supply rail respectively. The device does not need the specific power sequence between VCCA and VCCB during power-up or power-down. So, any power supply can be ramped up or down first. The device also provides high-impedance I/O mode to minimize the power consumption. When the input for EN pin is low, all I/O pins on A port and B port are placed in the high- impedance state. The device integrated 10 k pull-up resistors on the I/O lines on A port and B port to VCCA and VCCB power supply rail respectively. The SM5520 is available in 8-UDFN.
