NTS0308EPWJ

Translators, Level Shifters Overview

The NTS0308EPWJ is an 8-bit dual supply translating transceiver with open-drain outputs and auto direction sensing. It features eight bidirectional I/O ports (A and B), one output enable input (OE), and two supply pins, VCC(A) and VCC(B). VCC(A) operates between 0.95 V and 3.6 V, while VCC(B) operates between 1.65 V and 5.5 V, requiring VCC(A) ≤ VCC(B). The device supports a maximum data rate of 2 Mbps in open-drain mode and 20 Mbps in push-pull mode. It includes integrated ESD protection exceeding 2000 V HBM and 100 mA latch-up performance. Operating temperature ranges from -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for external control signals to manage data flow direction between voltage domains.
• Integrated edge-rate accelerator extends one-shot pulse duration to drive larger capacitive loads with reduced ringing and overshoot.
• Robust ESD protection meets IEC 61000-4-2 Class 4 standards on the B-side port and exceeds JESD22-A114E Class 2 for both ports.
• No power-sequencing requirements allow either supply rail to ramp up first without damaging the device.

Translators, Level Shifters Applications

• I2C and SMBus bus level translation
• UART interface voltage adaptation
• General Purpose Input Output (GPIO) expansion

Translators, Level Shifters FAQ

Does the NTS0308E require power sequencing during operation?

No, the device does not require special power-up sequencing. Either VCC(A) or VCC(B) can be powered up first without risk of damage, although VCC(A) must remain less than or equal to VCC(B) during normal operation.

How does the device handle data direction control?

The NTS0308E features auto direction sensing, which automatically detects the direction of data flow between the A and B ports without requiring an additional control signal.
