SN74LXC8T245PWR

The SN74LXC8T245PWR from Texas Instruments is an 8-bit, dual-supply, noninverting, bidirectional voltage level translation device. It is designed for applications requiring flexible voltage translation between different logic levels.

This transceiver features a fully configurable dual-rail design, allowing each port to operate independently from 1.1 V to 5.5 V. It supports data rates up to 420 Mbps for 3.3 V to 5.0 V translations. The device includes integrated dynamic pull-down resistors on I/Os and static pull-down resistors on control inputs, helping to reduce external component count and allowing for floating control inputs.

Key electrical characteristics include a high drive strength of up to 32 mA at 5 V and low power consumption, with a maximum of 4 µA at 25°C and 12 µA from -40°C to 125°C. The device also incorporates VCC isolation and VCC disconnect (Ioff-float) features, ensuring I/Os become high-impedance if either VCC supply drops below 100 mV or is disconnected. Latch-up performance exceeds 100 mA per JESD 78, Class II, and ESD protection exceeds 4000 V for the Human-Body Model and 1000 V for the Charged-Device Model.

The SN74LXC8T245PWR is available in a 24-TSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C. Applications include general purpose I/O level shifting, push-pull level shifting for interfaces like UART, SPI, and JTAG, and driving indicator LEDs or buzzers.
