SN74LXC2T45DCUR is a 2‑bit bidirectional dual‑supply bus transceiver with configurable voltage level shifting manufactured by TI, packaged in VSSOP‑8 tape‑and‑reel form, supporting 1.1 V to 5.5 V independent supply rails on each port, delivering up to 420 Mbps data rate, featuring Ioff‑float isolation and Schmitt‑trigger inputs for robust mixed‑voltage signal conversion across‑40 °C to +125 °C industrial temperature range for consumer, automotive and industrial hardware designs.
Key Features & Applications
● Dual‑rail flexible level translation with VCCA and VCCB ranging from 1.1 V to 5.5 V, enabling bidirectional logic conversion between different voltage domains.
● Schmitt‑trigger inputs with integrated pull‑down resistors enhance noise immunity and eliminate external pull‑down component requirements.
● VCC isolation and Ioff‑float function places I/Os into high‑impedance state when any supply rail is disconnected for partial‑power‑down protection.
● High‑speed performance up to 420 Mbps under 3.3 V‑to‑5.0 V conversion, low quiescent current of 6 µA maximum and 32 mA output drive strength at 5 V.
● Wide‑range industrial temperature rating, robust ESD and latch‑up compliance, VSSOP‑8 compact surface‑mount package for space‑constrained PCBs.
This bidirectional level shifter is widely deployed for GPIO, UART, JTAG and general‑purpose signal translation in portable consumer electronics, industrial sensor interfaces, automotive auxiliary modules, FPGA and MCU peripheral interfaces, battery‑powered IoT devices and mixed‑voltage communication links where compact size and reliable cross‑domain signal conversion are essential.
FAQ
Q: What key design notes apply to SN74LXC2T45DCUR?
A: Set DIR control signal according to VCCA logic level, maintain proper power supply sequencing, and leverage built‑in pull‑downs; avoid exceeding maximum data rate for low‑voltage translation paths to prevent signal integrity degradation.
