SGM4552X

1-Bit Bidirectional Voltage-Level Translator

for Open-Drain and Push-Pull Applications

GENERAL DESCRIPTION

FEATURES

The SGM4552X 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 V_CCAsupply and V_CCBsupply respectively. The

supply voltage range is 1.65V to 5.5V for A port and

2.3V to 5.5V for B port. The device provides a

bidirectional translation function between the different

voltage nodes (including 1.8V, 2.5V, 3.3V and 5V).

● Power Supply Voltage Ranges (V_CCA≤ V_CCB

 A Port: 1.65V to 5.5V

)

 B Port: 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 SGM4552X 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 +125℃ Operating Temperature Range

● Available in a Green SC70-6 Package

The SGM4552X is available in a Green SC70-6

package. It operates over an ambient temperature

range of -40℃ to +125℃.
