SGM4574YUQN12G/TR

The SGM4574 is a 4-bit, non-inverting, bidirectional voltage-level translator from SG Micro Corp. It features two independent configurable power-supply lines, VCCA and VCCB, allowing for flexible voltage translation between different logic levels. The A ports operate with supply voltages ranging from 1.65V to 5.5V, while the B ports support voltages from 2.3V to 5.5V. This device is suitable for translating between common voltage nodes such as 1.8V, 2.5V, 3.3V, and 5V.

Key electrical specifications include data rates of up to 24Mbps for push-pull applications and 2Mbps for open-drain configurations. The SGM4574 includes an output enable (OE) function that places all I/Os into a high-impedance state when low. It operates reliably within an ambient temperature range of -40°C to +85°C.

This translator is available in several package types, including UTQFN-1.8x1.8-12L, TQFN-2x2-12L, SOIC-14, and TQFN-3.5x3.5-14AL, all designed for surface mounting. The device does not require a specific power sequence for VCCA and VCCB and does not need a direction-control signal, simplifying integration into various electronic systems.

Applications for the SGM4574 include portable devices, smartphones, handheld devices, and PC/tablet systems where voltage level shifting is required between different components or subsystems.
