GENERAL DEscriptION

The SGM4574 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 1.65V to 5.5V for A ports and 2.3V to 5.5V for B ports. The device provides a bidirectional translation function between the different voltage nodes (including 1.8V, 2.5V, 3.3V and 5V).

The SGM4574 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. 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 SGM4574 features the OE input circuit which is referenced to VCCA.

The SGM4574 is available in Green UT×1.8-12L, TQFN-2×2-12L and SOIC-14 packages. It operates over an ambient temperature range of -40℃ to +85℃.
