SN74AUP1T34DCKR

The SN74AUP1T34DCKR from Texas Instruments is a 1-bit, non-inverting, unidirectional voltage-level translator designed for low-voltage applications. It features two separate configurable power-supply rails, VCCA and VCCB, both accepting supply voltages from 0.9V to 3.6V. This allows for seamless translation between various voltage nodes, including 1V, 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V.

Key electrical characteristics include a wide operating VCC range, balanced propagation delays, and low static-power consumption with a maximum ICC of 5µA. The device offers ±6mA output drive at 3V and supports partial power-down applications with its Ioff circuitry, which prevents damaging current backflow when the device is powered down. The VCC isolation feature ensures the B port remains in a high-impedance state if VCCA is at GND.

This translator is housed in a compact 5-TSSOP, SC-70-5, or SOT-353 package, suitable for surface mounting. It operates within a temperature range of -40°C to 85°C. The SN74AUP1T34DCKR also includes input hysteresis for better noise immunity and ESD protection exceeding 5000V (HBM).

With its versatile voltage translation capabilities and low power consumption, the SN74AUP1T34DCKR is well-suited for applications requiring interfacing between different voltage domains in portable devices, consumer electronics, and industrial systems.
