NTS0104PW-Q100J

Translators, Level Shifters Overview

The NTS0104PW-Q100J is a 4-bit dual-supply translating transceiver with auto direction sensing, designed for bidirectional voltage level translation. It features two 4-bit input-output ports (An and Bn), one output enable input (OE), and two supply pins (VCCA and VCCB). VCCA operates between 1.65 V and 3.6 V, while VCCB operates between 2.3 V and 5.5 V. The device supports maximum data rates of 50 Mbps in push-pull configurations. It includes IOFF circuitry for partial power-down applications to prevent backflow current. Qualified to AEC-Q100 Grade 1, it functions from -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Auto direction sensing enables bidirectional voltage level translation without external control signals.
• IOFF circuitry provides partial power-down mode operation by disabling outputs to prevent damaging backflow current.
• Inputs accept voltages up to 5.5 V, facilitating interface between different voltage domains.
• High ESD protection capabilities exceeding specified thresholds for both A and B ports.

Translators, Level Shifters Applications

• I2C/SMBus interfaces
• UART connections
• GPIO expansion

Translators, Level Shifters Procurement Notes

Verify the component matches the specific automotive grade qualification requirements for your design. Confirm that the TSSOP-14 package variant aligns with your PCB footprint specifications. Ensure that the supply voltage ranges on both sides of the translator are within the recommended operating conditions defined in the datasheet. Check for any specific marking codes required for traceability in your manufacturing process.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V nodes is required. It is suitable for open-drain drivers commonly used in I2C or 1-wire protocols. Consider the internal pull-up resistors and edge-rate acceleration features for signal integrity. Ensure the application does not require push-pull driving on both sides simultaneously at high speeds, as other variants may be more suitable.
