GENERAL DEscriptION

The SGM4563 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 SGM4563 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 SGM4563 features the OE input circuit which is referenced to VCCA.

The direction of three channels is from A to B, and the other channel is from B to A, so SGM4563 is the ideal device to finish the level translation of SPI bus or UART interface.

The SGM4563 is available in Green SOIC-14 and UT×1.8-12L packages. It operates over an ambient temperature range of -40℃ to +85℃
