Describe：

4-channel bidirectional voltage level converters, featuring automatic direction detection function. Port A supports voltages ranging from 1.2V to 3.6V, while Port B supports voltages from 1.65V to 5.5V. This enables universal low-voltage bidirectional conversion between different voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V). The data rate is up to 100Mbps, and the output type is tri-state, non-inverted. This device has ±15kV ESD protection (for Port B), and is suitable for smartphones, industrial control, and various embedded systems that require communication in different voltage domains.

Features ：

• Wide voltage range: Port A 1.2V ~ 3.6V, Port B 1.65V ~ 5.5V (with the requirement that VCCA ≤ VCCB)

• High-speed data transmission: Data rate up to 100Mbps, meeting the requirements of high-speed interfaces

• Automatic direction detection: No need for external direction control signals, simplifying the design

• 4 bidirectional channels: 4 independent channels, supporting bidirectional signal transmission

• Output type: Tri-state output, non-inverting structure

• ESD protection: The B port has ±15kV human body discharge model (HBM) protection, while the A port has 2500V HBM protection.

• Low power consumption: The maximum static current is only 5 µA.

• VCC isolation feature: If any VCC input is grounded, all outputs will be in a high-impedance state.

• Ioff power-down support: When the device loses power, it outputs a high-impedance state to prevent damaging reverse current.

• Wide operating temperature range: Industrial grade temperature range -40°C to +85°C

• Compact packaging: UQFN-12 ultra-thin square flat leadless package, with a size of only 1.7mm × 2.0mm

• Environmental compliance: Meets RoHS standards, lead-free, MSL grade 1 (unrestricted)

Application：

• IO expansion and level matching for smartphones and tablets

• Industrial automation control equipment

• Automotive electronics (infotainment systems, dashboards)

• Communication equipment (routers, switches)

• Cross-voltage domain interface communication for consumer electronic products

• Level conversion between sensors and microcontrollers

• General bidirectional voltage conversion scenario
