NTS0101GN,132

Translators, Level Shifters Overview

The NTS0101GN,132 is a 1-bit dual supply translating transceiver with auto direction sensing and open-drain outputs. It enables bidirectional voltage level translation between VCC(A) (1.65 V to 3.6 V) and VCC(B) (2.3 V to 5.5 V). The device supports maximum data rates of 50 Mbps in push-pull mode. It features IOFF circuitry for partial power-down applications, preventing damaging backflow currents when powered down. Inputs accept voltages up to 5.5 V, and it offers high ESD protection exceeding 8000 V HBM on the B port.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for an extra control signal to manage data flow direction between ports A and B.
• IOFF circuitry provides partial power-down mode operation by disabling outputs to prevent damaging backflow current during power loss.
• Integrated output edge-rate accelerator detects and accelerates rising edges to improve signal transition times.
• Internal pull-up resistors are included on both I/O ports for DC current sourcing capability.

Translators, Level Shifters Applications

• I2C/SMBus interfaces
• UART connections
• GPIO level shifting

Translators, Level Shifters Procurement Notes

Verify the specific package variant against the ordering information table, as the GN suffix corresponds to the SOT1202 XSON6 package. Confirm the temperature range requirement matches the datasheet specifications of -40°C to +125°C. Ensure that the system design accounts for the internal 10 kΩ pull-up resistors on both ports and their impact on the VOL level. Check that VCC(A) does not exceed VCC(B) during normal operation, although power-up sequencing flexibility exists.

Translators, Level Shifters Selection Notes

Select this component for point-to-point applications requiring translation between devices operating at different supply voltages, specifically targeting I2C or 1-wire protocols using open-drain drivers. Consider the NTB0101 if push-pull drivers are connected to the ports, as it may be more suitable for those scenarios. Ensure the external driver has an output impedance below 50 Ω to meet the specified dynamic characteristics limits.

Translators, Level Shifters Part Context

The NTS0101 belongs to NXP's family of voltage level translators designed for interfacing systems with different logic levels. It utilizes a switch-type architecture with a pass-gate transistor and an output edge-rate accelerator. This design allows for transparent bidirectional data transfer without explicit direction control signals, making it efficient for low-pin-count applications.

Translators, Level Shifters FAQ

Can VCC(A) be higher than VCC(B) during power-up?

Yes, during power-up, VCC(A) can be greater than or equal to VCC(B) without damaging the device, allowing either supply to ramp up first.

How does the device handle data direction?

The NTS0101 uses auto direction sensing, meaning it does not require an extra input signal to control the direction of data flow between port A and port B.
