TXU0101QDRYRQ1

Overview

The TXU0101QDRYRQ1 is an automotive-grade, single-bit fixed-direction voltage-level translator manufactured by Texas Instruments. It features Schmitt-trigger inputs and 3-state outputs for reliable signal translation between dual-rail logic systems. The device supports supply voltages from 1.1 V to 5.5 V on both ports, enabling flexible interface configurations. It offers data rates up to 200 Mbps at 3.3 V to 5.0 V levels. Key electrical characteristics include a maximum operating temperature of +125°C and low power consumption with a typical supply current of 2.5 µA at 25°C.

Feature Summary

• Schmitt-trigger inputs provide noise immunity for slow or noisy signals
• VCC isolation and Ioff-float feature disable outputs when supplies are disconnected
• OE control logic allows enable/disable referencing from either supply rail
• Integrated static pull-down resistors prevent channel floating

Applications

• Eliminating slow or noisy input signals in automotive circuits
• Driving indicator LEDs or buzzers
• Debouncing mechanical switches
• General purpose I/O level shifting
• Push-pull level shifting for UART, SPI, and JTAG interfaces

Procurement Notes

Verify the Q1 suffix indicates AEC-Q100 qualification for automotive use. Confirm the DRY package designation corresponds to the SON-6 footprint. Ensure the ordering part number matches the specific tape-and-reel quantity requirements for your production line. Cross-reference the datasheet revision date to confirm the latest electrical specifications.

Selection Notes

Select this component when a fixed unidirectional translation path from port A to port B is required. The device is suitable for applications needing high drive strength and robust ESD protection. Consider the dual-supply capability if interfacing between disparate voltage domains. Verify that the OE pin configuration aligns with the system's power management strategy.

Part Context

This part belongs to the TXU0101-Q1 family of translating transceivers designed for automotive environments. It provides a compact solution for bidirectional bus isolation with fixed directionality. The device integrates protection features essential for harsh automotive electrical conditions, ensuring reliability across the extended temperature range specified for automotive electronics.
