SGM4553YXET

2-Bit Bidirectional Voltage-Level Translator

for Open-Drain and Push-Pull Applications

GENERAL DESCRIPTION

FEATURES

The SGM4553YXET is

2-bit, non-inverting,

● Power Supply Voltage Ranges (V_CCA≤ V_CCB

 A Ports: 1.65V to 5.5V

)

bidirectional voltage-level translator which features two

independent configurable power-supply lines. The A

and B ports track the V_CCAsupply and V_CCBsupply

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 among the

different voltage nodes (including 1.8V, 2.5V, 3.3V and

5V).

 B Ports: 2.3V to 5.5V

● Direction-Control Signal is Not Required

● Data Rates

 Push-Pull: 24Mbps

 Open-Drain: 2Mbps

● Support V_CCAor V_CCBIsolation

 When V_CCAor V_CCBis Low, Device Enters

Power-Down Mode

The SGM4553YXET 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 V_CCAis powered,

OE has an internal pull-down current source.

● No Specific Power Sequences Required for V_CCA

and V_CCB

● Support Power-Down Mode

● -40℃ to +85℃ Operating Temperature Range

● Available in a Green XTDFN-1.35×1-8L Package

The SGM4553YXET is available in
