NTS0104BQ-Q100X

Translators, Level Shifters Overview

The NTS0104BQ-Q100X 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 (VCC(A) and VCC(B)). VCC(A) operates between 1.65 V and 3.6 V, while VCC(B) operates between 2.3 V and 5.5 V. The device supports maximum data rates of 50 Mbps in push-pull mode. It includes IOFF circuitry for partial power-down applications to prevent damaging backflow current. Qualified to AEC-Q100 Grade 1 standards, it functions within an ambient temperature range of -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, disabling outputs to prevent damaging backflow current.
• Inputs accept voltages up to 5.5 V, facilitating interface between different voltage nodes.
• High ESD protection performance 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 specific package type DHVQFN-14-EP (SOT762-1) matches the design footprint requirements. Confirm that the ordering suffix Q100 indicates automotive qualification to AEC-Q100 Grade 1 standards. Ensure supply voltage sequencing respects the operational limits where VCC(A) must not exceed VCC(B) during normal operation, although power-up sequencing flexibility exists.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems operating at different supply voltages, specifically between the 1.8 V/2.5 V/3.3 V domain and the 3.3 V/5.0 V domain. The open-drain architecture with internal pull-ups makes it suitable for I2C or 1-wire applications. Consider the NTB0104-Q100 if push-pull driver support is required instead of open-drain. Verify PCB layout constraints regarding capacitive loading and trace length to ensure proper one-shot triggering.

Translators, Level Shifters Part Context

The NTS0104-Q100 belongs to NXP's portfolio of dual-supply translating transceivers designed for automotive and industrial environments. It is part of a family including variants like the NTB0104 (push-pull) and NTS0104PW (TSSOP package). The BQ suffix denotes the DHVQFN14 package option, offering a compact solution for space-constrained designs requiring robust voltage translation capabilities.
