SGM4564 4-Bit Bidirectional Voltage-Level Translator with Auto Direction Sensing
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.
