TI SN65HVD78DRBR

These devices feature robust 3.3V drivers and receivers in compact packages, suitable for industrial applications. The bus pins are ESD-protected, offering high-level protection against the Human Body Model and IEC contact discharge specifications.

Each device integrates one differential driver and one differential receiver. Both devices operate from a single 3.3V supply. The driver differential output and receiver differential input are internally connected, forming a bus port suitable for half-duplex (2-wire bus) communication. The wide common-mode voltage range makes these devices well-suited for long-cable applications. These devices are rated for an operating temperature range of -40°C to 125°C.
