2-Bit Bidirectional Voltage-Level Translator for Open-Drain and Push-Pull Applications
2-Bit Bidirectional Voltage-Level Translator for Open-Drain and Push-Pull Applications
GENERAL DESCRIPTION

The SGM4553YTD is a 2-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 SGM4553YTD 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 SGM4553YTD is available in a Green TDFN-2×3-8BL package. It operates over an ambient temperature range of -40 to +85.
