SN74AUP1T34QDCKRQ1 - Texas Instruments Single-Bit Dual-Supply Voltage Level Translator

The SN74AUP1T34QDCKRQ1 is a high-performance, single-bit voltage level translator device from Texas Instruments, designed to facilitate communication between devices operating at different voltage levels. This component is part of the AUP (Advanced Ultra-Low Power) family, which is renowned for its low power consumption and high-speed operation, making it an ideal choice for battery-operated and power-sensitive applications.

With its dual-supply voltage capability, the SN74AUP1T34QDCKRQ1 allows for bidirectional voltage translation between two logic levels ranging from 0.8V to 3.6V on the A side (VCCA) and 1.2V to 3.6V on the B side (VCCB). This feature enables seamless integration of devices with mismatched I/O voltage levels, such as interfacing a low-voltage microcontroller with higher-voltage peripherals.

The device is housed in a compact 6-pin SC70 package, which is suitable for space-constrained applications. It also features a high-impedance output when disabled and a low ON-state resistance, providing minimal signal distortion and ensuring reliable data transmission. The SN74AUP1T34QDCKRQ1 supports both push-pull and open-drain configurations, adding to its versatility in various design scenarios.

Key specifications of the SN74AUP1T34QDCKRQ1 include:

• Wide VCCA and VCCB range: 0.8V to 3.6V (VCCA), 1.2V to 3.6V (VCCB)
• Low static power consumption: I<sub>CC is less than 0.9 µA at 3.6V
• High-speed operation: t<sub>pd is 3.7 ns (max) at 3.3V
• ESD protection exceeds JESD 22
• Latch-up performance exceeds 100 mA per JESD 78, Class II

The SN74AUP1T34QDCKRQ1 is also automotive qualified (Q1) and is built to meet the stringent requirements of the automotive industry, ensuring robust performance in harsh environments. It is an ideal solution for automotive applications, as well as for portable electronics, data communication systems, and anywhere level translation is required for interfacing different logic levels.

Whether you are designing a new system or upgrading an existing one, the SN74AUP1T34QDCKRQ1 by Texas Instruments provides a reliable and efficient way to bridge the gap between incompatible logic levels, simplifying the design process and enhancing overall system performance.
