GENERAL DESCRIPTION

The SGM4564 is a 4-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 1.2V to 5.5V for A ports and 1.65V to 5.5V for B ports.The device provides a bidirectional translation function between the different voltage nodes(including 1.2V,1.5V,1.8V,2.5V,3.3V and 5V).

The SGM4564 has an output enable(OE)function,which controls the outputs states.When OE goes low,all outputs enter into the high-impedance state.The OE should be connected to GND via a pull-down resistor,and the minimum resistor value is depended on the current source capability of the driver.

The SGM4564 features the OE input circuit which isreferenced to VCCA.

The SGM4564 is available in Green SOIC-14,UTQFN-1.8×1.8-12L and TQFN-2×2-12L packages.It operates over an ambient temperature range of-40℃to+85℃.
