1-Bit Bidirectional Voltage-Level Translator with Auto Direction Sensing
1-Bit Bidirectional Voltage-Level Translator with Auto Direction Sensing
GENERAL DESCRIPTION

The SGM4554 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 1.2V to 5.0V for A port and 1.65V to 5.5V for B port. 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 SGM4554 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 SGM4554 is available in Green UTDFN-1.45×1-6L and SC70-6 packages. It operates over an ambient temperature range of -40 to +85.
