NXB0108PWJ

Translators, Level Shifters Overview

The NXB0108PWJ is an 8-bit dual supply translating transceiver with auto direction sensing and 3-state outputs, manufactured by Nexperia USA Inc. It operates within a VCC(A) range of 1.2 V to 3.6 V and a VCC(B) range of 1.65 V to 5.5 V. The device supports data rates up to 110 Mbps and features propagation delays as low as 4.2 ns. It includes IOFF circuitry for partial power-down applications and is housed in a TSSOP20 (SOT360-1) package.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for explicit control signals to manage bidirectional data flow between ports.
• IOFF circuitry prevents damaging backflow currents when either supply voltage is powered down.
• High ESD protection capabilities exceed standard requirements for both Human Body Model and Charged Device Model events.

Translators, Level Shifters Applications

• Voltage level translation between systems operating at different supply voltages
• Partial power-down mode operation requiring isolation during power loss
• Bidirectional interface connections between microcontrollers and peripheral devices

Translators, Level Shifters Procurement Notes

Verify that the specific ordering suffix matches the required temperature range and package variant. Confirm that the application design accounts for the maximum supply voltage limits on both ports. Ensure that pull-up or pull-down resistors on I/O lines remain above 50 kΩ to prevent output contention issues due to the device's low static drive strength.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between dissimilar logic families is required without external direction control pins. It is suitable for interfaces where one side operates at lower voltages such as 1.2 V or 1.8 V while the other side utilizes higher levels like 3.3 V or 5.0 V. Consider the NXS0108 if open-drain applications are necessary instead.

Translators, Level Shifters Part Context

This device belongs to the NXB series of translating transceivers from Nexperia. It provides an 8-bit wide interface capable of handling high-speed data transfers. The PWJ designation indicates the TSSOP20 plastic thin shrink small outline package variant designed for surface mount technology assembly.

Translators, Level Shifters FAQ

Can VCC(A) be higher than VCC(B) during normal operation?

No, during operation VCC(A) must never be higher than VCC(B). However, during power-up sequences, VCC(A) can be greater than VCC(B) without damaging the device.

Is this device suitable for I2C bus applications?

No, the NXB0108 is not recommended for open-drain driver applications such as I2C or 1-Wire due to its push-pull output architecture and low static drive strength.
