The SGM4552 is a 1-bit, non-inverting, bidirectional voltage-level translator which features two independent configurable power-supply lines. The A and B ports track the VCCA supply and VCCB supply respectively. The supply voltage range is 1.65V to 5.5V for A port and 2.3V to 5.5V for B port. The device provides a bidirectional translation function between the different voltage nodes (including 1.8V, 2.5V, 3.3V and 5V).
The SGM4552 has an output enable (OE) function, which controls the inputs and outputs states. When OE goes low, all I/Os enter into the high-impedance state. It is beneficial for reducing quiescent current consumption. When VCCA is powered, OE has an internal pull-down current source.
The SGM4552 is available in Green SOT-23-6, SC70-6 and UTDFN-1.45×1-6L packages. It operates over an ambient temperature range of -40℃ to +85℃.
