SGM4563

4-Bit Level Translator

for SPI Bus or UART Interface

GENERAL DESCRIPTION

FEATURES

The SGM4563 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 V_CCAsupply and V_CCBsupply 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).

● Power Supply Voltage Range (V_CCA≤ V_CCB

 A Ports: 1.2V to 5.5V

)

 B Ports: 1.65V to 5.5V

● Support V_CCAor V_CCBIsolation

 When V_CCAor V_CCBis Low, Device Enters

Power-Down Mode

● The Direction of Channel 1, 2 and 3 is from A to B,

The Direction of Channel 4 is from B to A

● OE Input Circuit Referenced to V_CCA

● Support Partial-Power-Down Function

● Support Push-Pull Output

The SGM4563 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.

● Low Power Consumption

● -40℃ to +85℃ Operating Temperature Range

● Available in Green SOIC-14 and UTQFN-1.8×1.8-12L

Packages

The SGM4563 features the OE input circuit which is

referenced to V_CCA

APPLICATIONS

The direction of three channels is from A to B, and the

other channel is from B to A, so SGM4563 is the ideal

device to finish the level translation of SPI bus or UART

interface.
